Remove table header background styling (v1.7.6)

Removed custom background colors from table headers to improve preview appearance and maintain consistency with normal theming.

## Changes
- Removed background-color from default theme table headers (was #f6f8fa)
- Removed dark theme table header background styling block
- Headers retain font-weight: 600 for visual distinction
- Table borders and alternating row colors remain intact

## User Request
User feedback: "remove the theming of table headers, it looks bad. Keep normal theming of preview"

-# Security Assessment Report: MarkdownConverter v4.0.0
-
-**Assessment Date:** 2026-03-15
-**Application:** MarkdownConverter - Electron-based Markdown editor and document converter
-**Target Version:** 4.0.0
-**Assessor:** Security Audit Agent
-
----
-
-## Executive Summary
-
-This assessment identified **10 security findings** ranging from **Critical to Low severity**. The most significant concerns involve insecure Electron security configuration that could allow XSS attacks to escalate to full system access, arbitrary code execution via the REPL feature, and missing input validation on file operations.
-
-| Severity | Count |
-|----------|-------|
-| Critical | 2 |
-| High | 3 |
-| Medium | 3 |
-| Low | 2 |

-## Vulnerability Findings
-
-### CVE-MC-001: Insecure Electron Security Configuration (Critical)
-
-**CVSS 3.1 Score: 9.6 (Critical)**
-**CWE-265: CWE-1021: Improper Restriction of Renderers**
-
-**Location:** `src/main.js` (lines 328-332)
-
-```javascript
-webPreferences: {
-  nodeIntegration: true,
-  contextIsolation: false,
-  spellcheck: true
-},
-```
-
-**Description:**
-The main application window has `nodeIntegration: true` and `contextIsolation: false`, which is the most insecure Electron configuration. This allows the renderer process direct access to Node.js APIs, meaning any XSS vulnerability in the markdown rendering or external content could lead to full system compromise.
-
-**Exploitability:**
-- An attacker who can inject malicious JavaScript (via markdown files, XSS in preview, or compromised dependencies) gains immediate access to:
-  - Full file system read/write via `fs` module
-  - Command execution via `child_process`
-  - Network access via `net` module
-  - All system resources
-
-**Attack Scenario:**
-1. User opens a malicious markdown file containing embedded JavaScript
-2. The JavaScript executes in the renderer with full Node.js access
-3. Attacker can read sensitive files, execute commands, exfiltrate data
-
-**Remediation:**
-```javascript
-webPreferences: {
-  nodeIntegration: false,
-  contextIsolation: true,
-  sandbox: true,
-  preload: path.join(__dirname, 'preload.js')
-}
-```
-
-**Note:** The preload.js file already implements a secure IPC bridge but it is not being utilized for the main window.
-
----
-
-### CVE-MC-002: Arbitrary Code Execution via REPL Feature (Critical)
-
-**CVSS 3.1 Score: 9.3 (Critical)**
-**CWE-94: Improper Control of Generation of Code ('Code Injection')**
-
-**Location:** `src/main.js` (lines 4369-4396)
-
-**Description:**
-The `execute-code` IPC handler allows execution of arbitrary Python and Bash scripts through the REPL panel. While JavaScript execution appears to have been removed or limited, Python and Bash commands are executed via `execFile` with user-supplied code.
-
-**Vulnerable Code Pattern:**
-```javascript
-ipcMain.handle('execute-code', async (event, { code, language }) => {
-  // ...
-  if (language === 'python' || language === 'py') {
-    cmd = 'python';
-    args = ['-c', code];
-  }
-  // ...
-  execFile(cmd, args, { timeout }, (err, stdout, stderr) => {
-    // ...
-  });
-});
-```
-
-**Exploitability:**
-- Users can be tricked into running malicious code blocks
-- Markdown files can contain executable code blocks with "Run" buttons
-- No sandboxing or permission restrictions on executed code
-
-**Attack Scenario:**
-1. Attacker creates markdown file with malicious Python code block
-2. User clicks "Run" button in preview
-3. Python code executes with user's full permissions
-4. Attacker gains code execution on victim's machine
-
-**Remediation:**
-- Remove arbitrary code execution feature entirely, OR
-- Implement strict sandboxing (Docker, VM, or restricted Python environment)
-- Add user confirmation dialogs with clear warnings
-- Execute in isolated environment with no filesystem/network access
-- Implement allowlist of safe operations
-

-
-### CVE-MC-003: Potential XSS in Markdown Rendering (High)
-
-**CVSS 3.1 Score: 8.0 (High)**
-**CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')**
-
-**Location:** `src/renderer.js` (lines 387-419)
-
-**Description:**
-While DOMPurify is used to sanitize HTML, several extensions to marked.js may bypass sanitization:
-
-1. **Custom Admonition Extension (lines 51-77):**
-```javascript
-marked.use({
-    extensions: [{
-        name: 'admonition',
-        // ...
-        renderer(token) {
-            const inner = this.parser.parse(token.text);
-            return `<div class="admonition admonition-${token.admonitionType}">
-                <div class="admonition-title">${icon} ${token.admonitionType...}</div>
-                <div class="admonition-content">${inner}</div>
-            </div>`;
-        }
-    }]
-});
-```
-
-2. **innerHTML Assignments (line 419):**
-```javascript
-preview.innerHTML = sanitizedHtml;
-```
-
-**Exploitability:**
-- Combined with CVE-MC-001, XSS leads to full system compromise
-- Custom markdown extensions may not be properly sanitized
-- Admonition type is directly interpolated into HTML without escaping
-
-**Remediation:**
-- Ensure all custom markdown extensions escape user input
-- Add Content Security Policy that blocks inline scripts
-- Use `textContent` instead of `innerHTML` where possible
-- Audit all custom marked.js extensions for XSS vectors
-

-
-### CVE-MC-004: Missing Path Traversal Protection (High)
-
-**CVSS 3.1 Score: 7.8 (High)**
-**CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')**
-
-**Location:** `src/main.js` (lines 4241-4281)
-
-**Description:**
-The `list-directory` and `open-file-path` IPC handlers accept arbitrary file paths without validation:
-
-```javascript
-ipcMain.handle('list-directory', async (event, dirPath) => {
-  try {
-    if (!dirPath) { /* dialog */ }
-    // No path validation - accepts any path
-    const entries = fs.readdirSync(dirPath, { withFileTypes: true });
-    // ...
-  }
-});
-
-ipcMain.on('open-file-path', (event, filePath) => {
-  // No path validation
-  if (!fs.existsSync(filePath)) return;
-  const content = fs.readFileSync(filePath, 'utf-8');
-  mainWindow.webContents.send('file-opened', { path: filePath, content });
-});
-```
-
-**Exploitability:**
-- Malicious renderer code can read any file on the system
-- No restriction to a sandbox directory
-- Combined with XSS, attacker can exfiltrate sensitive files
-
-**Remediation:**
-```javascript
-const ALLOWED_DIRECTORIES = [app.getPath('documents'), app.getPath('desktop')];
-
-function isPathAllowed(filePath) {
-  const resolved = path.resolve(filePath);
-  return ALLOWED_DIRECTORIES.some(dir => resolved.startsWith(dir));
-}
-```
-
----
-
-### CVE-MC-005: Weak Content Security Policy (High)
-
-**CVSS 3.1 Score: 7.5 (High)**
-**CWE-1021: Improper Restriction of Renderers**
-
-**Location:** `src/index.html` (line 5)
-
-```html
-<meta http-equiv="Content-Security-Policy" content="default-src 'self';
-  script-src 'self' 'unsafe-inline' 'unsafe-eval' https://cdn.jsdelivr.net;
-  style-src 'self' 'unsafe-inline' https://cdnjs.cloudflare.com;
-  img-src 'self' data: blob: file:;
-  font-src 'self' data:;
-  connect-src 'self' https://www.plantuml.com;">
-```
-
-**Description:**
-The CSP contains several security weaknesses:
-
-1. **`'unsafe-inline'` in script-src** - Allows inline script injection
-2. **`'unsafe-eval'` in script-src** - Allows `eval()` and similar functions
-3. **`https://cdn.jsdelivr.net`** - Allows scripts from external CDN (supply chain risk)
-4. **`file:` in img-src** - Allows loading local files as images (potential information disclosure)
-
-**Exploitability:**
-- XSS attacks can execute arbitrary scripts
-- External CDN compromise could inject malicious code
-- `eval()` enables dynamic code execution
-
-**Remediation:**
-- Remove `'unsafe-inline'` and `'unsafe-eval'`
-- Use nonces or hashes for inline scripts
-- Remove external CDNs or use Subresource Integrity (SRI)
-- Remove `file:` from img-src
-
----
-
-### CVE-MC-006: Insecure Window Configuration for PDF Export (Medium)
-
-**CVSS 3.1 Score: 6.5 (Medium)**
-**CWE-1021: Improper Restriction of Renderers**
-
-**Location:** `src/main.js` (lines 2579-2585)
-
-```javascript
-const pdfWindow = new BrowserWindow({
-  show: false,
-  webPreferences: {
-    nodeIntegration: true,
-    contextIsolation: false
-  }
-});
-```
-
-**Description:**
-Hidden windows created for PDF export also have insecure configurations, allowing potential privilege escalation.
-
-**Remediation:**
-```javascript
-webPreferences: {
-  nodeIntegration: false,
-  contextIsolation: true,
-  sandbox: true
-}
-```
-
----
-
-### CVE-MC-007: PlantUML Server Data Exfiltration (Medium)
-
-**CVSS 3.1 Score: 5.3 (Medium)**
-**CWE-359: Exposure of Private Information**
-
-**Location:** `src/renderer.js` (lines 470-487)
-
-```javascript
-const plantumlBlocks = preview.querySelectorAll('pre code.language-plantuml');
-plantumlBlocks.forEach((block) => {
-    const code = block.textContent;
-    // ...
-    const encoded = plantumlEncode(code);
-    const img = document.createElement('img');
-    img.src = `https://www.plantuml.com/plantuml/svg/${encoded}`;
-    // ...
-});
-```
-
-**Description:**
-PlantUML diagram content is sent to an external server (plantuml.com) for rendering. This could leak sensitive information contained in diagrams.
-
-**Exploitability:**
-- Diagrams containing proprietary information, system architecture, or internal processes are sent to third-party servers
-- No user consent or notification before external data transmission
-
-**Remediation:**
-- Use local PlantUML rendering with Java
-- Add user warning before sending data to external service
-- Implement opt-in for external rendering
-
----
-
-### CVE-MC-008: Inconsistent Security Settings Across Windows (Medium)
-
-**CVSS 3.1 Score: 5.5 (Medium)**
-**CWE-1021: Improper Restriction of Renderers**
-
-**Description:**
-Security settings are inconsistent across different windows:
-
-| Window | nodeIntegration | contextIsolation | Security |
-|--------|-----------------|------------------|----------|
-| Main Window | true | false | Insecure |
-| About Dialog | false | true | Secure |
-| Dependencies Dialog | false | true | Secure |
-| ASCII Generator | false | true | Secure |
-| Table Generator | false | true | Secure |
-| PDF Export Window | true | false | Insecure |
-| Hidden Conversion Window | true | false | Insecure |
-
-**Remediation:**
-Apply secure configuration (`nodeIntegration: false`, `contextIsolation: true`) consistently across all windows.
-
----
-
-### CVE-MC-009: Command Execution via External Tools (Low)
-
-**CVSS 3.1 Score: 4.4 (Low)**
-**CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')**
-
-**Location:** `src/main.js` (lines 1915-1972)
-
-**Description:**
-While the application uses `execFile` instead of `exec` (good practice), external tools (Pandoc, LibreOffice, FFmpeg, ImageMagick) are invoked with file paths that could potentially be manipulated.
-
-**Positive Finding:**
-The code correctly uses `execFile` with argument arrays instead of shell commands, mitigating most command injection vectors.
-
-**Remaining Risk:**
-- File paths are not validated against malicious names
-- Special characters in filenames could cause issues with external tools
-
-**Remediation:**
-- Validate file paths before passing to external tools
-- Sanitize filenames of special characters
-
----
-
-### CVE-MC-010: Missing Dependency Version Pinning (Low)
-
-**CVSS 3.1 Score: 3.5 (Low)**
-**CWE-1035: Using Components with Known Vulnerabilities**
-
-**Location:** `package.json`
-
-**Description:**
-Dependencies use `^` version ranges which could allow automatic updates to versions with vulnerabilities:
-
-```json
-"dependencies": {
-  "marked": "^17.0.3",
-  "dompurify": "^3.3.1",
-  "mermaid": "^11.12.3",
-  // ...
-}
-```
-
-**Remediation:**
-- Pin exact versions in production
-- Use lockfile (package-lock.json)
-- Implement dependency scanning in CI/CD pipeline

-## Positive Security Findings
-
-1. **Preload.js Implementation:** A secure IPC bridge with channel whitelisting is implemented
-2. **DOMPurify Usage:** HTML sanitization is applied to markdown output
-3. **execFile Usage:** External commands use `execFile` instead of `exec`
-4. **File Size Limits:** 50MB maximum file size is enforced
-5. **Rate Limiting:** Conversion operations have rate limiting (2 second minimum interval)
-6. **Error Message Sanitization:** Absolute paths are stripped from error messages
-
----
-
-## Prioritized Remediation Roadmap
-
-### Phase 1 - Critical (Immediate)
-1. Set `nodeIntegration: false` and `contextIsolation: true` for main window
-2. Remove or sandbox the code execution (REPL) feature
-3. Implement proper preload.js usage for all windows
-
-### Phase 2 - High Priority (1-2 Weeks)
-4. Add path traversal protection to file operations
-5. Strengthen Content Security Policy
-6. Audit and fix custom markdown extensions for XSS
-
-### Phase 3 - Medium Priority (1 Month)
-7. Implement consistent security settings across all windows
-8. Add local PlantUML rendering option
-9. Implement dependency scanning in CI/CD
-
-### Phase 4 - Low Priority (Ongoing)
-10. Pin dependency versions
-11. Add security headers to all generated HTML
-12. Implement security logging and monitoring
-
----
-
-## Compliance Considerations
-
-- **OWASP Top 10 2021:** A03:2021 - Injection, A05:2021 - Security Misconfiguration
-- **OWASP ASVS:** V12 - File Handling, V13 - API Security
-- **NIST CSF:** PR.AC - Access Control, PR.DS - Data Security
-
----
-
-## Conclusion
-
-The MarkdownConverter application has significant security vulnerabilities that could allow an attacker to execute arbitrary code, access sensitive files, and compromise the user's system. The most critical issue is the insecure Electron configuration combined with XSS attack vectors in the markdown rendering pipeline.
-
-**Overall Security Rating: HIGH RISK**
-
-The positive finding is that much of the security infrastructure (preload.js, DOMPurify) is already in place but not properly utilized. With focused remediation effort, the application can achieve a much stronger security posture.

-# Comprehensive UI Design Review - MarkdownConverter Electron Application
-
-## Executive Summary
-
-This review covers the UI design of the MarkdownConverter Electron application, analyzing visual design, usability, code quality, and performance across all UI files. The application has a solid foundation but has several areas requiring attention.
-
----
-
-## 1. Visual Design Review
-
-### 1.1 Spacing & Layout Consistency
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | Inconsistent padding values across files | Multiple CSS files | Standardize to 4px/8px base scale |
-| **Major** | Multiple reset declarations | `styles.css:1-5`, `styles-modern.css:42-47` | Consolidate resets into single file |
-| **Minor** | Tab padding varies between themes | `styles.css:36`, `styles-modern.css:101` | Use CSS variables for consistent padding |
-| **Minor** | Container padding inconsistency | `styles.css:17-21`, `styles-modern.css:63-69` | Define single container style |
-
-**Code Example - Duplicate Reset:**
-
-```css
-/* styles.css:1-5 */
-* {
-    margin: 0;
-    padding: 0;
-    box-sizing: border-box;
-}
-
-/* styles-modern.css:42-47 - DUPLICATE */
-* {
-  margin: 0;
-  padding: 0;
-  box-sizing: border-box;
-}
-```
-
-**Fix Recommendation:**
-```css
-/* Create a single base.css or remove from styles-modern.css */
-/* Use CSS variables for spacing scale */
-:root {
-  --space-1: 4px;
-  --space-2: 8px;
-  --space-3: 12px;
-  --space-4: 16px;
-  --space-5: 24px;
-  --space-6: 32px;
-}
-```
-
-### 1.2 Typography Consistency
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | Font-family declared multiple times with different fallbacks | `styles.css:8`, `styles-modern.css:50`, `styles-concreteinfo.css:32` | Standardize font stack |
-| **Major** | Duplicate font-size declarations | `styles.css:228-230` | Remove duplicate |
-| **Minor** | Inconsistent line-height values | Multiple files | Create type scale variables |
-
-**Code Example - Duplicate font-size:**
-```css
-/* styles.css:226-230 */
-.preview-content {
-    max-width: none;
-    margin: 0;
-    padding: 20px 24px 24px 24px;
-    line-height: 1.6;
-    font-size: 15px;
-    font-size: 14px;  /* DUPLICATE - overwrites previous */
-}
-```
-
-**Fix Recommendation:**
-```css
-/* styles.css - Remove duplicate */
-.preview-content {
-    font-size: 14px;  /* Keep only one */
-    line-height: 1.6;
-}
-```
-
-### 1.3 Color Usage and Contrast Accessibility
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Critical** | Hardcoded colors instead of CSS variables | `styles.css:27-29`, `styles.css:37-38`, etc. | Use CSS custom properties |
-| **Major** | Inconsistent gray scale definitions | Multiple files define different grays | Consolidate to single palette |
-| **Minor** | Some contrast ratios may be insufficient | Status bar text colors | Verify WCAG 2.1 AA compliance |
-
-**Code Example - Hardcoded colors:**
-```css
-/* styles.css:27-29 */
-.tab-bar {
-    background: #f0f0f0;  /* Should use var(--gray-100) */
-    border-bottom: 1px solid #ddd;  /* Should use var(--gray-300) */
-}
-```
-
-**Fix Recommendation:**
-```css
-/* Use the existing palette from styles-modern.css */
-.tab-bar {
-    background: var(--gray-100, #f3f4f6);
-    border-bottom: 1px solid var(--gray-300, #d1d5db);
-}
-```
-
-### 1.4 Dark Mode Support Quality
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | Dark theme selectors inconsistent | `styles.css` uses `body.theme-dark`, `styles-sidebar.css:108` uses `body[class*="dark"]` | Standardize selector pattern |
-| **Minor** | Missing dark theme support for some components | `.breadcrumb-bar`, command palette | Add dark mode variants |
-| **Suggestion** | Repetitive dark theme declarations | `styles-concreteinfo.css:362-425` | Use CSS custom properties for theming |
-
-**Code Example - Inconsistent selectors:**
-```css
-/* styles.css */
-body.theme-dark .tab-bar { ... }
-
-/* styles-sidebar.css */
-body[class*="dark"] .sidebar-icons { ... }
-```
-
-**Fix Recommendation:**
-```css
-/* Choose one pattern and apply consistently */
-/* Option 1: Class-based (recommended) */
-body.theme-dark .tab-bar,
-body.theme-dark .sidebar-icons { ... }
-
-/* Option 2: Attribute-based */
-body[data-theme="dark"] .tab-bar { ... }
-```
-
----
-
-## 2. Usability Review
-
-### 2.1 Clickable/Tappable Areas
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Critical** | Tab close button too small (16x16px) | `styles.css:62-77` | Increase to minimum 24x24px |
-| **Major** | Sidebar icons at minimum size | `styles-sidebar.css:35-47` (36x36px) | Consider 40-44px for better touch |
-| **Minor** | Toolbar buttons at edge of minimum | `styles.css:120-131` (32x32px) | Acceptable for mouse, small for touch |
-
-**Code Example - Small close button:**
-```css
-/* styles.css:62-77 */
-.tab-close {
-    width: 16px;   /* TOO SMALL - below 24px minimum */
-    height: 16px;  /* TOO SMALL */
-}
-```
-
-**Fix Recommendation:**
-```css
-.tab-close {
-    width: 24px;
-    height: 24px;
-    border-radius: 4px;
-}
-
-/* Add touch-friendly hit area */
-.tab-close::before {
-    content: '';
-    position: absolute;
-    top: -4px;
-    left: -4px;
-    right: -4px;
-    bottom: -4px;
-}
-```
-
-### 2.2 Hover/Focus States
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Critical** | Missing focus-visible styles | All interactive elements | Add :focus-visible for keyboard navigation |
-| **Major** | No focus indicators on toolbar buttons | `styles.css:133-140` | Add visible focus ring |
-| **Minor** | Inconsistent hover transitions | Various components | Standardize transition duration |
-
-**Code Example - Missing focus styles:**
-```css
-/* styles.css:120-131 - No focus state */
-.toolbar button {
-    /* ... no focus style */
-}
-
-.toolbar button:hover {
-    background: #e0e0e0;
-    border-color: #ccc;
-}
-```
-
-**Fix Recommendation:**
-```css
-.toolbar button:focus-visible {
-    outline: 2px solid var(--primary-dark, #5661b3);
-    outline-offset: 2px;
-}
-
-.toolbar button:hover {
-    background: #e0e0e0;
-    border-color: #ccc;
-}
-```
-
-### 2.3 Loading and Error State Handling
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | Generic error message without styling | `renderer.js:384-386`, `renderer.js:508-511` | Create styled error components |
-| **Minor** | No loading indicators for async operations | Sidebar panels | Add skeleton loaders or spinners |
-| **Minor** | `git-loading` class exists but minimal styling | `styles-sidebar.css:227` | Enhance with animation |
-
-**Code Example - Plain error display:**
-```javascript
-// renderer.js:384-386
-preview.innerHTML = '<p style="color: red; padding: 20px;">Error: Required libraries...';
-// Inline styles should be in CSS
-```
-
-**Fix Recommendation:**
-```css
-/* Add to styles.css */
-.preview-error {
-    display: flex;
-    flex-direction: column;
-    align-items: center;
-    justify-content: center;
-    padding: 40px 20px;
-    color: var(--ci-danger, #dc3545);
-    text-align: center;
-}
-
-.preview-error-icon {
-    font-size: 48px;
-    margin-bottom: 16px;
-}
-```
-
-### 2.4 Accessibility (ARIA, Semantic HTML)
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Critical** | Buttons without accessible labels | `index.html:31` (tab close), `index.html:33` (new tab) | Add aria-label |
-| **Critical** | SVG icons lack aria-hidden | All toolbar buttons | Add aria-hidden="true" |
-| **Major** | Missing role attributes on tabs | `index.html:29-33` | Add role="tablist", role="tab" |
-| **Major** | No skip links | `index.html` | Add skip to main content link |
-| **Minor** | Dialog missing aria-modal | Export dialogs | Add aria-modal="true" |
-
-**Code Example - Missing accessibility attributes:**
-```html
-<!-- index.html:31 - Current -->
-<button class="tab-close" title="Close tab">x</button>
-
-<!-- index.html:33 - Current -->
-<button class="new-tab-button" id="new-tab-btn" title="New tab">+</button>
-```
-
-**Fix Recommendation:**
-```html
-<!-- Improved with ARIA -->
-<div class="tab-bar" id="tab-bar" role="tablist" aria-label="Document tabs">
-    <div class="tab active" data-tab-id="1" role="tab" aria-selected="true" aria-controls="tab-content-1">
-        <span class="tab-title">Untitled</span>
-        <button class="tab-close" aria-label="Close tab" title="Close tab">×</button>
-    </div>
-    <button class="new-tab-button" id="new-tab-btn" aria-label="Create new tab" title="New tab">+</button>
-</div>
-
-<!-- SVG icons should have aria-hidden -->
-<button id="btn-bold" title="Bold (Ctrl+B)" aria-label="Bold">
-    <svg width="16" height="16" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" aria-hidden="true">
-        ...
-    </svg>
-</button>
-```
-
-### 2.5 Keyboard Navigation
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | Tab order may skip sidebar icons | Sidebar panel | Verify logical tab order |
-| **Minor** | No escape key handling for dialogs | Export dialogs | Add escape to close |
-| **Minor** | Find dialog lacks full keyboard support | `renderer.js:804-866` | Add Ctrl+F shortcut hint |

-## 3. Code Quality Review
-
-### 3.1 CSS Organization & Naming
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | No clear CSS architecture | All CSS files | Adopt BEM or similar methodology |
-| **Major** | Overly generic class names | `.pane`, `.tab`, `.container` | Use more specific naming |
-| **Minor** | Mixed naming conventions | camelCase (`tabBar`), kebab-case (`tab-bar`) | Standardize to kebab-case |
-| **Minor** | Magic numbers | Various pixel values | Replace with spacing variables |
-
-### 3.2 CSS Specificity Issues
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | Excessive use of `!important` | `styles.css:14` | Restructure to avoid |
-| **Major** | Deep selector nesting | Dark theme selectors | Flatten and use CSS variables |
-| **Minor** | ID selectors for styling | `styles.css:233-247` | Prefer class selectors |
-
-**Code Example - Problematic specificity:**
-```css
-/* styles.css:14 - Avoid !important */
-.hidden {
-    display: none !important;
-}
-
-/* styles.css:397-431 - Deep nesting */
-body.theme-dark #preview h1,
-body.theme-dark [id^="preview-"] h1,
-body.theme-dark .preview-content h1 {
-    color: #c9d1d9;
-    border-bottom-color: #21262d;
-}
-```
-
-**Fix Recommendation:**
-```css
-/* Use utility class pattern */
-[hidden] { display: none; }
-
-/* Use CSS custom properties for theming */
-.preview-content h1 {
-    color: var(--text-primary);
-    border-bottom-color: var(--border-color);
-}
-
-/* Theme applies variables */
-body.theme-dark {
-    --text-primary: #c9d1d9;
-    --border-color: #21262d;
-}
-```
-
-### 3.3 Reusable Style Definitions
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | Repeated button styles | Multiple files | Create button component classes |
-| **Major** | Dialog styles duplicated | Export, batch, print preview dialogs | Create modal component |
-| **Minor** | Similar form field styles scattered | Export dialog inputs | Create form component |
-
-**Code Example - Duplicated button styles:**
-```css
-/* styles.css */
-.toolbar button { /* button styles */ }
-.tab-close { /* button styles */ }
-.new-tab-button { /* button styles */ }
-#export-dialog-close { /* button styles */ }
-
-/* styles-sidebar.css */
-.sidebar-icon { /* similar button styles */ }
-.sidebar-panel-close { /* similar button styles */ }
-```
-
-**Fix Recommendation:**
-```css
-/* Create button component system */
-.btn {
-    display: inline-flex;
-    align-items: center;
-    justify-content: center;
-    border: none;
-    cursor: pointer;
-    transition: all var(--transition-fast);
-}
-
-.btn--icon {
-    width: 32px;
-    height: 32px;
-    border-radius: var(--radius-md);
-}
-
-.btn--close {
-    font-size: 14px;
-    font-weight: bold;
-    border-radius: var(--radius-sm);
-}
-```
-
-### 3.4 Documentation
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Minor** | Limited CSS documentation | All CSS files | Add section comments |
-| **Minor** | No component documentation | Sidebar components | Add JSDoc-style comments |
-| **Suggestion** | No design tokens documentation | CSS variables | Create tokens documentation |
-
----
-
-## 4. Performance Review
-
-### 4.1 CSS Optimization
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | Large CSS files (105KB main, 78KB modern) | `styles.css`, `styles-modern.css` | Split into smaller modules |
-| **Major** | Duplicate style definitions | Multiple files | Remove redundancies |
-| **Minor** | Unused styles likely present | Theme variations | Audit and remove unused |
-
-### 4.2 Asset Loading
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Major** | highlight.js CSS loaded synchronously | `index.html:14` | Load asynchronously or bundle |
-| **Minor** | Font files could be preloaded | `fonts.css` | Add preload links in HTML |
-| **Suggestion** | Consider CSS critical path | Above-the-fold styles | Inline critical CSS |
-
-**Code Example - Sync stylesheet loading:**
-```html
-<!-- index.html:14 - Blocks rendering -->
-<link rel="stylesheet" href="../node_modules/highlight.js/styles/default.css">
-```
-
-**Fix Recommendation:**
-```html
-<!-- Non-blocking load -->
-<link rel="stylesheet" href="../node_modules/highlight.js/styles/default.css" media="print" onload="this.media='all'">
-
-<!-- Or preload fonts -->
-<link rel="preload" href="../assets/fonts/Inter-Regular.woff2" as="font" type="font/woff2" crossorigin>
-```
-
-### 4.3 Animation Performance
-
-| Severity | Issue | Location | Recommendation |
-|----------|-------|----------|----------------|
-| **Minor** | Some transitions on expensive properties | `styles-modern.css:111-112` | Prefer transform/opacity |
-| **Suggestion** | Missing will-change hints | Complex animations | Add will-change for GPU hints |
-
----
-
-## 5. Component-Specific Issues
-
-### 5.1 Tab System
-
-| File | Issues |
-|------|--------|
-| `styles.css:23-97` | Inconsistent active state styling, small close button |
-| `renderer.js:88-346` | Tab content created via innerHTML (XSS risk) |
-
-### 5.2 Sidebar
-
-| File | Issues |
-|------|--------|
-| `styles-sidebar.css` | Good structure but missing focus states |
-| `sidebar-manager.js` | Clean implementation, needs ARIA |
-
-### 5.3 Export Dialogs
-
-| File | Issues |
-|------|--------|
-| `styles.css:1060-1355` | Monolithic, should be component |
-| `index.html:171-331` | Complex nested structure needs semantic HTML |
-
-### 5.4 Welcome Screen
-
-| File | Issues |
-|------|--------|
-| `styles-welcome.css` | Minimal styles, good foundation |
-| Missing hover states for keyboard focus | Add :focus-visible |
-
----
-
-## 6. Prioritized Fix Recommendations
-
-### Critical (Immediate)
-
-1. **Add missing ARIA attributes** to all interactive elements
-2. **Increase tab close button size** to minimum 24x24px
-3. **Add focus-visible styles** for keyboard navigation
-4. **Fix duplicate font-size declaration** in `.preview-content`
-
-### Major (Next Sprint)
-
-1. **Consolidate CSS resets** into single location
-2. **Create button component system** with variants
-3. **Standardize dark theme selectors** across all files
-4. **Replace hardcoded colors** with CSS variables
-5. **Create modal/dialog component** to reduce duplication
-
-### Minor (Future)
-
-1. **Document CSS architecture** and naming conventions
-2. **Audit and remove unused styles**
-3. **Add loading state components** (skeletons, spinners)
-4. **Implement CSS module splitting** for better performance
-
----
-
-## 7. Summary Statistics
-
-| Category | Critical | Major | Minor | Suggestions |
-|----------|----------|-------|-------|-------------|
-| Visual Design | 1 | 5 | 4 | 1 |
-| Usability | 3 | 4 | 4 | 0 |
-| Code Quality | 0 | 6 | 4 | 1 |
-| Performance | 0 | 3 | 2 | 2 |
-| **Total** | **4** | **18** | **14** | **4** |
-
----
-

-# Repository Guidelines
-
-## Project Structure & Module Organization
-Core application code lives in `src/`. Use `src/main.js` for the Electron main process, `src/preload.js` for the preload bridge, and `src/renderer.js` plus `src/editor/`, `src/sidebar/`, `src/repl/`, and `src/utils/` for renderer-side features. Electron adapter code is in `src/adapters/electron/`. Reusable markdown/document templates live in `src/templates/`. Static assets and icons are in `assets/`. Tests are in `tests/`, and build output goes to `dist/`.
-
-## Build, Test, and Development Commands
-- `npm start`: launch the Electron app locally.
-- `npm test`: run the Jest suite once.
-- `npm run test:watch`: rerun tests during local development.
-- `npm run test:coverage`: generate coverage output.
-- `npm run lint` / `npm run lint:fix`: check or fix ESLint issues in `src` and `tests`.
-- `npm run format` / `npm run format:check`: apply or verify Prettier formatting.
-- `npm run build:linux`, `npm run build:win`, `npm run build:mac`: create platform packages with `electron-builder`.
-
-## Coding Style & Naming Conventions
-This repo uses Prettier and ESLint. Follow `.prettierrc`: 2-space indentation, single quotes, semicolons, trailing commas where valid in ES5, and a 100-character line width. Prefer `camelCase` for variables/functions, `PascalCase` for classes, and kebab-case for file names only when already established. Keep module boundaries clear: UI logic in renderer modules, OS/file-system work behind Electron IPC and adapters.
-
-## Testing Guidelines
-Tests use Jest with `jest-environment-jsdom`. Add new tests under `tests/` with `*.test.js` names, mirroring the feature area when possible, for example `tests/sidebar.test.js` or `tests/print-preview.test.js`. Update or add regression tests for renderer behavior, preload APIs, and utility helpers when fixing bugs. Run `npm test` before opening a PR; use `npm run test:coverage` for larger refactors.
-
-## Commit & Pull Request Guidelines
-Recent history follows Conventional Commit prefixes such as `feat:`, `fix:`, and `refactor:`. Keep subjects short and imperative, for example `fix: guard modal cleanup on close`. PRs should describe the user-visible change, note test coverage, link any related issue, and include screenshots or GIFs for UI changes.
-
-## Security & Configuration Tips
-Do not bypass preload boundaries or introduce direct `eval`/dynamic code paths; ESLint already treats these as errors. Export and conversion features depend on external tools such as Pandoc, FFmpeg, ImageMagick, and LibreOffice, so document any new runtime dependency in `README.md` and packaging config.

-
-## [5.0.0] - 2026-06-06
-
-### Added
-- **Complete React 19 + Vite + TypeScript renderer** replacing the legacy vanilla-JS UI (Phases 1-9 of the React UI redesign)
-- Native macOS/Windows/Linux menus with command palette and keyboard shortcuts
-- Settings sheet with 5 tabs (editor, theme, keybindings, advanced, about) and 17+ persisted fields
-- Modal layer with 13 modal kinds (export PDF/DOCX/HTML/Word, batch, settings, about, welcome, confirm, ASCII gen, table gen, find in files)
-- 10 advanced tools: ASCII generator (figlet), table generator, Word export (.docx via `docx` lib), find-in-files (recursive regex), REPL (markdown snippet preview), print preview, zen mode (Esc exits), minimap, breadcrumbs-with-symbols, git status (porcelain parser)
-- Sonner toast notifications at 4 wire points (file save, open file/folder, 4 export dialogs)
-- 3 mount strategies: ModalLayer dialogs, App.tsx global overlays, editor/sidebar integrations
-- `ipc.file.writeBuffer` for renderer-side binary file output (used by Word .docx export)
-- `ipc.file.search` (recursive regex), `ipc.file.gitStatus`, `ipc.print.show`, `ipc.app.showSaveDialog`
-- 305 unit + integration tests (vitest + React Testing Library)
-- Per-package @radix-ui primitives (checkbox, dialog, select, switch, tabs, radio-group, scroll-area, slider, collapsible, label, context-menu)
-- shadcn/ui (new-york style) primitives, manually pasted (CLI broken on Node 24)
-- Feature-first main process decomposition: `src/main/{files,menu,window,word-template,utils}/` + glue files
-
-### Changed
-- **BREAKING**: Renderer is now React-only. The legacy `src/renderer.js` (5319 lines) and all vanilla-JS UI scripts/styles are removed.
-- Main process decomposed from a 4311-line `src/main.js` into feature-first modules under `src/main/`
-- New entrypoint: `src/main/index.js` (was `src/main.js`)
-- `src/index.html` (1667-line legacy orphan) removed; renderer served by `src/renderer/index.html` (Vite root)
-- IPC contract: handlers throw on error, `safeCall` catches → returns `{ ok: false, error }`. `result.ok` is at top level, NOT nested in `result.data.ok`
-- Settings store: `useSettingsStore` (zustand persist with zod validation), 17+ persisted fields
-- Modal state: `useAppStore.modal: ModalState` discriminated union with 13 kinds; `openModal` uses TS conditional types to enforce prop requirements
-
-### Removed
-- `src/renderer.js` (legacy vanilla-JS renderer, 5319 lines)
-- 8 legacy stylesheets: `src/styles.css`, `src/styles-modern.css`, `src/styles-concreteinfo.css`, `src/styles-sidebar.css`, `src/styles-zen.css`, `src/styles-welcome.css`, `src/fonts.css`
-- 5 legacy scripts: `src/command-palette.js`, `src/print-preview.js`, `src/welcome.js`, `src/zen-mode.js`, `src/wordTemplateExporter.js`
-- 2 legacy HTMLs: `src/ascii-generator.html`, `src/table-generator.html`
-- `src/main.js` (4311-line god file, replaced by `src/main/index.js`)
-- `src/index.html` (1667-line legacy orphan at project root, replaced by `src/renderer/index.html`)
-- 9 dead IPC channels from `src/preload.js`: `toggle-command-palette`, `print-preview`, `print-preview-styled`, `open-ascii-generator`, `open-table-generator`, `show-ascii-generator`, `show-ascii-generator-window`, `show-table-generator`, `show-table-generator-window`

-## 10. Appendix
-
-### A. Security Configuration Audit
-
-**Main Window (main.js:323-334)**
-```javascript
-// CURRENT (INSECURE)
-webPreferences: {
-  nodeIntegration: true,      // CRITICAL: Allows require() in renderer
-  contextIsolation: false,    // CRITICAL: No isolation between contexts
-  spellcheck: true
-}
-
-// RECOMMENDED
-webPreferences: {
-  nodeIntegration: false,
-  contextIsolation: true,
-  sandbox: true,
-  spellcheck: true,
-  webSecurity: true,
-  allowRunningInsecureContent: false
-}
-```
-
-**CSP Configuration (index.html:5)**
-```html
-<!-- CURRENT (WEAK) -->
-<meta http-equiv="Content-Security-Policy"
-  content="default-src 'self';
-           script-src 'self' 'unsafe-inline' 'unsafe-eval' https://cdn.jsdelivr.net;
-           ...">
-
-<!-- RECOMMENDED -->
-<meta http-equiv="Content-Security-Policy"
-  content="default-src 'self';
-           script-src 'self';
-           style-src 'self';
-           img-src 'self' data:;
-           connect-src 'self';
-           frame-src 'none';
-           object-src 'none'">
-```
-

-
----
-
-## 3. State Management (Zustand)
-
-### Editor Store
-
-```typescript
-interface Tab {
-  id: string;
-  title: string;
-  content: string;
-  filePath?: string;
-  isDirty: boolean;
-  cursorPosition: { line: number; column: number };
-}
-
-interface EditorState {
-  tabs: Tab[];
-  activeTabId: string | null;
-
-  // Actions
-  createTab: (title?: string) => string;
-  closeTab: (id: string) => void;
-  setActiveTab: (id: string) => void;
-  updateContent: (id: string, content: string) => void;
-  updateCursorPosition: (id: string, pos: { line: number; column: number }) => void;
-  markSaved: (id: string, filePath?: string) => void;
-}
-```
-
-### Settings Store
-
-```typescript
-interface SettingsState {
-  theme: string;
-  fontSize: number;
-  fontFamily: string;
-  previewMode: 'split' | 'editor' | 'preview';
-  showLineNumbers: boolean;
-  wordWrap: boolean;
-  autoSave: boolean;
-  autoSaveInterval: number;
-}
-```
-
-**Stores Summary:**
-
-| Store | State | Persisted |
-|-------|-------|-----------|
-| `editorStore` | Tabs, content, cursor | Tab metadata only |
-| `settingsStore` | User preferences | Yes |
-| `themeStore` | Active theme, custom themes | Yes |
-| `sidebarStore` | Panel state, width | Yes |
-
----
-
-## 4. Platform Adapters
-
-### Adapter Interface
-
-```typescript
-export interface PlatformAdapter {
-  name: 'tauri' | 'web';
-
-  // File System
-  fs: {
-    readFile: (path: string) => Promise<string>;
-    writeFile: (path: string, content: string) => Promise<void>;
-    deleteFile: (path: string) => Promise<void>;
-    listDirectory: (path: string) => Promise<FileInfo[]>;
-    exists: (path: string) => Promise<boolean>;
-    watchDirectory?: (path: string, callback: WatchCallback) => () => void;
-  };
-
-  // Conversion
-  convert: {
-    toPdf: (content: string, options: PdfOptions) => Promise<Blob>;
-    toDocx: (content: string, options: DocxOptions) => Promise<Blob>;
-    toHtml: (content: string, options: HtmlOptions) => Promise<string>;
-    batchConvert: (files: string[], format: string) => Promise<ConversionResult[]>;
-  };
-
-  // Capabilities
-  capabilities: {
-    hasPandoc: boolean;
-    hasFfmpeg: boolean;
-    hasLibreOffice: boolean;
-    hasDirectFs: boolean;
-    hasSystemNotifications: boolean;
-  };
-}
-```
-
-### Platform Detection
-
-```typescript
-// Auto-detect platform at startup
-const isTauri = typeof window !== 'undefined' &&
-                '__TAURI__' in window;
-
-export const adapter: PlatformAdapter = isTauri
-  ? tauriAdapter
-  : webAdapter;
-```
-
-### Capability Differences
-
-| Feature | Tauri (Desktop) | Web (PWA) |
-|---------|-----------------|-----------|
-| File System | Direct access | IndexedDB + File System Access API |
-| PDF Export | Pandoc (native) | WASM converter |
-| DOCX Export | Pandoc (native) | Limited/not available |
-| Media Conversion | FFmpeg (native) | Cloud API or limited |
-| File Watching | Native events | Not available |
-| Offline | Always | Service Worker |

-# Modal System Design
-
-**Date:** 2026-03-24
-**Version:** 4.0.0
-**Status:** Approved
-
-## Overview
-
-Replace the existing dialog implementations with a unified modal system that provides:
-- Glassmorphism backdrop matching app aesthetic
-- Full accessibility (ARIA, focus trap, keyboard navigation)
-- Smooth fade + scale animations
-- Consistent API via `ModalManager` class
-
-## Decisions Made
-
-| Decision | Choice | Rationale |
-|----------|--------|-----------|
-| Architecture | Unified `ModalManager` class | Cleaner, consistent behavior across all modals |
-| Backdrop style | Glassmorphism | Matches existing app design language |
-| Focus management | Focus first interactive element | Standard, predictable behavior |
-| Animation | Fade + scale (95% → 100%) | Modern, subtle effect |
-| Implementation | Custom (not native `<dialog>`) | Full control, no polyfill concerns |
-
-## Architecture
-
-### File Structure
-
-```
-src/
-├── utils/
-│   └── ModalManager.js    # Core modal logic (~150 lines)
-├── styles/
-│   └── modal.css          # Unified modal styles (~200 lines)
-└── index.html             # Updated dialog markup
-```
-
-### ModalManager Class
-
-```javascript
-class ModalManager {
-  constructor(element, options = {})
-  open()                    // Show modal with animation
-  close()                   // Hide modal with animation
-  destroy()                 // Cleanup event listeners
-  on(event, callback)       // Event subscription
-
-  // Internal
-  #createBackdrop()         // Create glassmorphism backdrop
-  #trapFocus()              // Manage focus within modal
-  #handleKeydown(e)         // Escape key handler
-  #getFocusableElements()   // Query focusable children
-}
-```
-
-### Events
-
-- `open` — Fired after open animation completes
-- `close` — Fired after close animation completes
-
-## CSS Design
-
-### Variables (from tokens.css)
-
-```css
---z-modal: 200;
---transition-normal: 200ms cubic-bezier(0.4, 0, 0.2, 1);
---shadow-xl: 0 20px 25px -5px rgb(0 0 0 / 0.1);
---radius-lg: 0.5rem;
-```
-
-### Backdrop
-
-```css
-.modal-backdrop {
-  position: fixed;
-  inset: 0;
-  background: rgba(0, 0, 0, 0.4);
-  backdrop-filter: blur(4px);
-  -webkit-backdrop-filter: blur(4px);
-  z-index: var(--z-modal);
-}
-```
-
-### Modal Container
-
-```css
-.modal {
-  position: fixed;
-  inset: 0;
-  display: flex;
-  align-items: center;
-  justify-content: center;
-  z-index: calc(var(--z-modal) + 1);
-  opacity: 0;
-  visibility: hidden;
-  transition: opacity var(--transition-normal),
-              visibility var(--transition-normal);
-}
-
-.modal.open {
-  opacity: 1;
-  visibility: visible;
-}
-```
-
-### Modal Content (with animation)
-
-```css
-.modal-content {
-  background: hsl(var(--background));
-  border-radius: var(--radius-lg);
-  box-shadow: var(--shadow-xl);
-  max-width: 90vw;
-  max-height: 90vh;
-  overflow: hidden;
-  transform: scale(0.95);
-  transition: transform var(--transition-normal);
-}
-
-.modal.open .modal-content {
-  transform: scale(1);
-}
-```
-
-## HTML Structure
-
-All dialogs convert to unified structure:
-
-```html
-<div id="export-dialog"
-     class="modal"
-     role="dialog"
-     aria-modal="true"
-     aria-labelledby="export-dialog-title">
-
-  <div class="modal-backdrop" data-close></div>
-
-  <div class="modal-content">
-    <div class="modal-header">
-      <h3 id="export-dialog-title">Export Options</h3>
-      <button class="modal-close" aria-label="Close">&times;</button>
-    </div>
-
-    <div class="modal-body">
-      <!-- Dialog-specific content -->
-    </div>
-
-    <div class="modal-footer">
-      <button class="btn btn-secondary" data-close>Cancel</button>
-      <button class="btn btn-primary">Confirm</button>
-    </div>
-  </div>
-</div>
-```
-
-### Key Attributes
-
-- `role="dialog"` — Screen reader identification
-- `aria-modal="true"` — Prevents screen reader from accessing background
-- `aria-labelledby` — References the dialog title
-- `data-close` — Click handler for closing (backdrop, cancel buttons)
-
-## Accessibility Features
-
-1. **Focus trap** — Tab cycles within modal only
-2. **Focus first element** — Auto-focuses first input/button on open
-3. **Escape key** — Closes modal
-4. **Click outside** — Clicking backdrop closes modal
-5. **Focus restoration** — Returns focus to trigger element on close
-6. **ARIA attributes** — Proper screen reader support
-
-## Dialogs to Migrate
-
-| Dialog ID | Current Class | Complexity |
-|-----------|--------------|------------|
-| `find-dialog` | `.find-dialog` | Simple |
-| `export-dialog` | `.export-dialog` | Complex (many sections) |
-| `print-preview-overlay` | `.export-dialog` | Medium |
-| `table-generator-dialog` | `.export-dialog` | Simple |
-| `ascii-art-dialog` | `.export-dialog` | Medium |
-| `universal-converter-dialog` | `.export-dialog` | Complex |
-| `batch-dialog` | `.batch-dialog` | Complex |
-| `pdf-editor-dialog` | `.export-dialog` | Complex |
-| `header-footer-dialog` | `.export-dialog` | Medium |
-| `field-picker-dialog` | `.export-dialog` | Simple |
-
-## Migration Steps
-
-1. Create `src/utils/ModalManager.js`
-2. Create `src/styles/modal.css`
-3. Update `index.html` to include new stylesheet
-4. Convert each dialog HTML to new structure
-5. Initialize `ModalManager` instances in `renderer.js`
-6. Remove old CSS from `styles.css`
-7. Test all dialogs
-
-## Out of Scope
-
-- Modal nesting (stacked modals) — can be added later if needed
-- Animated backdrop (currently static blur)
-- Modal size variants (small/large/fullscreen) — can use inline styles

-# V4 Enhancement + Flutter Exploration Design
-
-**Date:** 2026-03-24
-**Status:** Approved
-**Approach:** Incremental V4 Enhancement + Flutter Spike (70/30 split)
-
----
-
-## Executive Summary
-
-This design outlines a two-track approach:
-1. **V4 Enhancement (70%)**: Fix critical bugs, optimize performance, add platform adapters, improve UI patterns
-2. **Flutter Exploration (30%)**: Build proof-of-concept for cross-platform evaluation (Windows, Mobile, Web)
-
----
-
-## Goals & Scope
-
-### Primary Goals
-1. **Fix critical bug**: PDF and markdown multitab functionality
-2. **Performance improvements**: Faster startup, smoother editing, responsive preview
-3. **Architecture improvements**: Platform adapters, cleaner state management
-4. **Flutter research**: Proof-of-concept for cross-platform evaluation
-
-### Out of Scope
-- Full V5 migration
-- Complete UI redesign
-- New features (focus on optimization)
-
-### Success Criteria
-
-| Metric | Current | Target |
-|--------|---------|--------|
-| Startup time | ~3-5s | <2s |
-| Editor typing latency | Noticeable lag | <16ms |
-| Preview render (1MB file) | ~500ms | <200ms |
-| Memory usage | ~300MB | <200MB |
-| Bundle size | ~150MB | <100MB |
-
----
-
-## Section 1: V4 Critical Fixes & Performance Optimizations
-
-### 1.1 Fix: PDF/Markdown Multitab Bug
-
-**Location:** `src/renderer.js` (TabManager class)
-
-**Investigation areas:**
-- `switchToTab()` - ensure proper state preservation
-- `closeTab()` - ensure EditorView cleanup
-- Add tab type tracking (markdown vs pdf)
-- Isolate PDF viewer state from editor state
-
-### 1.2 Startup Performance Optimizations
-
-| Optimization | Implementation | Expected Gain |
-|--------------|----------------|---------------|
-| Defer Mermaid | Load only when diagram detected | ~500ms |
-| Defer PDF.js | Load on first PDF open | ~800ms |
-| Lazy load themes | Load active theme only | ~200ms |
-| Lazy sidebar panels | Load panel code when sidebar opens | ~300ms |
-| Preload optimization | Remove unused IPC channels | ~100ms |
-
-**Lazy loading pattern:**
-```javascript
-// Current (loads everything upfront)
-const { dialog } = require('@electron/remote');
-
-// Optimized (load on demand)
-let _dialog;
-function getDialog() {
-  if (!_dialog) _dialog = require('@electron/remote').dialog;
-  return _dialog;
-}
-```
-
-### 1.3 Editor Performance
-
-| Issue | Solution |
-|-------|----------|
-| Typing lag with large files | Debounce preview updates (300ms) |
-| Syntax highlight overhead | Use highlight.js lazy mode |
-| Memory leaks | Clean up EditorView on tab close |
-| Theme switching lag | Pre-compile theme CSS |
-
-### 1.4 Preview Rendering
-
-| Issue | Solution |
-|-------|----------|
-| Mermaid slow | Render on-demand, cache results |
-| Full re-render on keystroke | Debounced incremental updates |
-| Large documents | Viewport rendering (visible portion only) |
-
----
-
-## Section 2: Platform Adapter Pattern
-
-### 2.1 Architecture
-
-```
-src/
-├── adapters/
-│   ├── index.js              # Auto-detects and exports adapter
-│   ├── types.js              # Interface definitions (JSDoc)
-│   │
-│   ├── electron/             # Current Electron implementation
-│   │   ├── index.js          # Exports electronAdapter
-│   │   ├── fs.js             # File system operations
-│   │   ├── convert.js        # Pandoc, FFmpeg conversions
-│   │   ├── pdf.js            # PDF operations
-│   │   └── system.js         # System info, dialogs, notifications
-│   │
-│   └── mock/                 # For testing
-│       └── index.js          # Mock adapter for unit tests
-```
-
-### 2.2 Adapter Interface
-
-```javascript
-/**
- * @typedef {Object} PlatformAdapter
- * @property {'electron'} name
- * @property {FileSystemAdapter} fs
- * @property {ConversionAdapter} convert
- * @property {PdfAdapter} pdf
- * @property {SystemAdapter} system
- */
-
-/**
- * @typedef {Object} FileSystemAdapter
- * @property {(path: string) => Promise<string>} readFile
- * @property {(path: string, content: string) => Promise<void>} writeFile
- * @property {(path: string) => Promise<void>} deleteFile
- * @property {(path: string) => Promise<FileInfo[]>} listDirectory
- * @property {(path: string) => Promise<boolean>} exists
- */
-```
-
-### 2.3 Migration Strategy
-
-| Phase | What | Files Affected |
-|-------|------|----------------|
-| 1 | Create adapter structure | New files only |
-| 2 | Migrate file operations | `renderer.js`, `sidebar/*.js` |
-| 3 | Migrate conversions | Export dialogs |
-| 4 | Migrate PDF operations | PDF viewer |
-| 5 | Remove old IPC calls | `preload.js` cleanup |
-
----
-
-## Section 3: UI Improvements (Shadcn/ui Patterns)
-
-### 3.1 Design Token System
-
-```css
-/* src/styles/tokens.css */
-
-:root {
-  /* Colors - Light mode */
-  --background: 0 0% 100%;
-  --foreground: 222.2 84% 4.9%;
-  --primary: 227 44% 52%;
-  --primary-foreground: 210 40% 98%;
-  --secondary: 210 40% 96.1%;
-  --secondary-foreground: 222.2 47.4% 11.2%;
-  --muted: 210 40% 96.1%;
-  --muted-foreground: 215.4 16.3% 46.9%;
-  --destructive: 0 84.2% 60.2%;
-  --border: 214.3 31.8% 91.4%;
-  --ring: 227 44% 52%;
-
-  /* Spacing & Radii */
-  --radius: 0.5rem;
-}
-```
-
-### 3.2 Component Improvements
-
-| Component | Current Issue | Fix |
-|-----------|---------------|-----|
-| Buttons | Inconsistent hover/focus | Use `.btn` with variants |
-| Dialogs | Missing focus trap | Add focus trap, Escape key, aria-modal |
-| Tabs | No keyboard navigation | Add arrow key nav, aria-selected |
-| Sidebar | No collapse animation | CSS transitions |
-| Dropdowns | Missing click-outside | Add proper event handling |
-
-### 3.3 Accessibility Improvements
-
-- Focus states with `:focus-visible`
-- Skip to content link
-- ARIA labels on interactive elements
-- Keyboard navigation for all components
-
----
-
-## Section 4: Flutter Exploration (30% Effort)

-# Writer's Studio Feature Pack — Design Document
-
-**Date**: 2026-04-06
-**Version**: 4.2.0 target
-**Status**: Approved
-**Scope**: Three cohesive features to transform MarkdownConverter into a writing environment
-
----
-
-## Overview
-
-The Writer's Studio Feature Pack adds three interconnected features to MarkdownConverter:
-
-1. **Zen Mode** — Distraction-free writing environment with typewriter scrolling
-2. **Document Outline** — Heading hierarchy sidebar panel for navigation
-3. **Writing Analytics** — Real-time readability and vocabulary analysis dashboard
-
-These features work together: Zen Mode creates the environment, Outline provides navigation, Analytics gives insight.
-
----
-
-## Feature 1: Zen Mode
-
-### Purpose
-
-Transform the app from a multi-tool into a focused writing environment. Inspired by iA Writer, Typora, and Bear.
-
-### New Files
-
-- `src/zen-mode.js` — ZenMode class (~150 lines)
-- `src/styles-zen.css` — Zen mode specific styles (~120 lines)
-
-### Integration Points
-
-- `src/renderer.js` — Initialize ZenMode, register F11 shortcut, add View > Zen Mode menu
-- `src/editor/codemirror-setup.js` — Export typewriter + dimming extensions
-
-### Behavior
-
-**Toggle**: F11, View > Zen Mode, command palette "Toggle Zen Mode"
-**Exit**: Escape key, F11 again
-
-**What hides**:
-- Tab bar
-- Toolbar
-- Sidebar (collapsed)
-- Status bar
-- App header
-
-**What shows**:
-- Editor (full viewport)
-- Floating HUD (bottom-center, semi-transparent)
-
-### Floating HUD
-
-```
-┌─────────────────────────────────────────┐
-│  847 words  •  ~4 min  •  23:45 session │
-│  ████████████████░░░░  85% of 1000      │
-└─────────────────────────────────────────┘
-```
-
-- Word count (from existing status bar logic)
-- Estimated reading time (~200 wpm)
-- Session timer (starts when zen mode activates)
-- Optional progress bar toward word goal
-
-### CodeMirror Extensions
-
-**Typewriter Scroll** (`ViewPlugin`):
-- Listens to `EditorView.update` for selection changes
-- Calls `editor.dispatch({ effects: EditorView.scrollIntoView(pos, { y: 'center' }) })`
-- Smooth scrolling with `scrollBehavior: 'smooth'` in CSS
-
-**Line Dimming** (`ViewPlugin` + `Decoration`):
-- Builds a `DecorationSet` mapping each line to an opacity value
-- Active line: opacity 1.0
-- 1-2 lines away: 0.7
-- 3-4 lines away: 0.5
-- 5+ lines away: 0.3
-- Uses `Decoration.line({ attributes: { style: 'opacity: X' } })`
-
-### Centered Column
-
-CSS applied to `.zen-mode .cm-content`:
-```css
-.zen-mode .cm-content {
-    max-width: 700px;
-    margin: 0 auto;
-    font-size: 18px;
-    line-height: 1.8;
-}
-```
-
-### State Management
-
-- `this.previousState` stores which UI elements were visible before zen mode
-- On exit, restores all elements to their previous visibility
-- Editor content, cursor position, and scroll state are never modified
-
----
-
-## Feature 2: Document Outline Panel
-
-### Purpose
-
-Provide always-visible heading navigation for documents of any length. The single most-requested navigation feature for multi-section documents.
-
-### New Files
-
-- `src/sidebar/outline-panel.js` — `renderOutlinePanel` function (~100 lines)
-
-### Modified Files
-
-- `src/index.html` — Add outline icon button in sidebar icons strip
-- `src/renderer.js` — Register 'outline' panel, provide editor reference
-
-### Sidebar Integration
-
-Uses existing `SidebarManager.registerPanel()` API:
-```javascript
-sidebarManager.registerPanel('outline', {
-    title: 'Outline',
-    render: (container) => renderOutlinePanel(container, editor, editorContent)
-});
-```
-
-New icon button in sidebar strip (after templates icon):
-```html
-<button class="sidebar-icon" data-panel="outline" title="Outline (Ctrl+Shift+O)">
-    <!-- hierarchy/list icon SVG -->
-</button>
-```
-
-### Parsing Logic
-
-Parse headings from raw markdown content using regex:
-```javascript
-const headingRegex = /^(#{1,6})\s+(.+)$/gm;
-```
-
-Returns array of:
-```javascript
-{ level: 1-6, text: "Heading Text", line: 42 }
-```
-
-Debounced at 300ms to avoid re-parsing on every keystroke.
-
-### UI Structure
-
-```
-┌──────────────────────────────────────────┐
-│  OUTLINE                          ☰      │
-├──────────────────────────────────────────┤
-│  ▸ Introduction                  (H1)    │
-│    ▸ Getting Started             (H2)    │
-│    ▸ Prerequisites               (H2)    │
-│      ▸ Node.js                   (H3) ◄  │
-│    ▸ Installation                (H2)    │

-│    ▸ Export                      (H2)    │
-├──────────────────────────────────────────┤
-│  9 headings  •  2 H1  •  4 H2  •  3 H3  │
-└──────────────────────────────────────────┘
-```
-
-- Indentation based on heading level (H1 = 0px, H2 = 16px, H3 = 32px, etc.)
-- Current heading highlighted with accent color (◄ indicator)
-- Hover shows full heading text if truncated
-
-### Click-to-Navigate
-
-```javascript
-editor.dispatch({
-    effects: EditorView.scrollIntoView(linePos, { y: 'center' })
-});
-```
-
-Brief highlight animation on the target line (fades out over 500ms).
-
-### Current Heading Sync
-
-On editor update (debounced 100ms):
-1. Get cursor line number
-2. Find the last heading whose line number <= cursor line
-3. Set that heading as active in the outline
-
-### Empty State
-
-When no headings found:
-```
-No headings found
-
-Use # to create headings:
-# Heading 1
-## Heading 2
-### Heading 3
-```
-
----
-
-## Feature 3: Writing Analytics
-
-### Purpose
-
-Give writers real-time insight into their document's readability, structure, and vocabulary. This is the "surprise" feature most Markdown editors lack.
-
-### New Files
-
-- `src/analytics/writing-analytics.js` — `WritingAnalytics` class (~180 lines)
-- `src/analytics/analytics-panel.js` — `renderAnalyticsPanel` function (~120 lines)
-
-### Integration Points
-
-- `src/renderer.js` — Register Ctrl+Shift+A shortcut, command palette entry, View menu item
-
-### Trigger

-### Metrics Implementation
-
-**Readability (Flesch-Kincaid):**
-```javascript
-// Flesch Reading Ease
-ease = 206.835 - 1.015 * (words / sentences) - 84.6 * (syllables / words);
-
-// Flesch-Kincaid Grade Level
-grade = 0.39 * (words / sentences) + 11.8 * (syllables / words) - 15.59;
-```
-
-**Syllable Estimation:**
-```javascript
-function countSyllables(word) {
-    word = word.toLowerCase().replace(/(?:[^laeiouy]es|ed|[^laeiouy]e)$/, '');
-    word = word.replace(/^y/, '');
-    return word.match(/[aeiouy]{1,2}/g)?.length || 1;
-}
-```
-
-**Reading/Speaking Time:**
-- Reading: 200 words/minute
-- Speaking: 130 words/minute
-
-**Lexical Diversity:**
-- Ratio of unique words to total words (excluding stop words)
-
-**Top Words:**
-- Frequency map, sorted descending, top 10
-- Excludes common stop words (the, a, an, is, are, etc.)
-
-### Word Goal
-
-- Persisted in `electron-store` per document (or global default)
-- Progress bar with percentage
-- Celebration effect when goal is reached (brief confetti animation or green flash)
-
-### Update Cadence
-
-- Re-analyzes on editor content change (debounced at 1000ms)
-- If modal is open, updates live
-- If modal is closed, no computation (zero overhead)

-# MarkdownConverter v5.0 — Platform Design
-
-**Date:** 2026-04-14
-**Status:** Approved
-**Author:** Amit Haridas
-
-## Overview
-
-Transform MarkdownConverter from a monolithic editor into an extensible platform with a plugin system and three feature packs, shipped together as v5.0.
-
-## Subsystems
-
-1. **Plugin System** — Lightweight plugin registry with extension points (sidebar, commands, settings, status bar, export hooks, event bus)
-2. **Writing Studio Plugin** — Manuscript manager, goal tracking, writing sprints, snapshots, smart proofreading
-3. **AI Assistant Plugin** — Multi-provider AI writing assistant (Ollama, LMStudio, GGUF direct with GPU, Anthropic, OpenAI)
-4. **Collaboration Plugin** — Git-based async collaboration, comments/annotations, review requests
-
-## Core Principle
-
-**Existing functionality is never replaced or broken.** The plugin system is additive. All existing keyboard shortcuts, features, and UI remain untouched. Plugin shortcuts use `Ctrl+Alt+` namespace.
-
----
-
-## 1. Plugin System
-
-### File Structure
-
-```
-src/
-  plugins/
-    plugin-registry.js      # Load, register, lifecycle
-    plugin-api.js            # Base class plugins extend
-    plugin-loader.js         # Discovers and validates manifests
-    built-in/
-      writing-studio/
-        manifest.json
-        index.js
-        panels/
-        components/
-      ai-assistant/
-        manifest.json
-        index.js
-        providers/
-      collaboration/
-        manifest.json
-        index.js
-```
-
-### Manifest Schema
-
-```json
-{
-  "id": "writing-studio",
-  "name": "Writing Studio",
-  "version": "1.0.0",
-  "description": "Manuscript management, goal tracking, writing sprints",
-  "icon": "pen-tool",
-  "extensionPoints": {
-    "sidebar": { "panel": "panels/manuscript-panel.js", "order": 30 },
-    "settings": { "section": "settings/index.js" },
-    "statusBar": { "indicators": ["sprint-timer", "word-goal"] },
-    "commands": [
-      { "id": "start-sprint", "label": "Start Writing Sprint", "shortcut": "Ctrl+Alt+S" },
-      { "id": "take-snapshot", "label": "Take Snapshot", "shortcut": "Ctrl+Alt+N" }
-    ],
-    "exportHooks": {
-      "preExport": "hooks/pre-export.js",
-      "postExport": "hooks/post-export.js"
-    }
-  },
-  "settings": [
-    { "key": "dailyGoal", "type": "number", "default": 1000, "label": "Daily word goal" },
-    { "key": "sprintDuration", "type": "number", "default": 25, "label": "Sprint duration (min)" }
-  ]
-}
-```
-
-### Plugin Lifecycle
-
-1. PluginLoader discovers manifests in `built-in/` + user plugins directory
-2. PluginRegistry validates manifests
-3. Each plugin calls `Plugin.init(context)` receiving scoped API context
-4. Extension points registered (sidebar panels, commands, status bar items)
-5. Plugins activate lazily — sidebar panel loads JS when user clicks tab
-
-### Plugin Context API
-
-Each plugin's `init()` receives:
-
-```javascript
-{
-  sidebar: {
-    registerPanel(id, { icon, title, component })
-  },
-  commands: {
-    register(id, label, handler, shortcut?)
-  },
-  statusBar: {
-    registerIndicator(id, { position, render })
-  },
-  settings: {
-    get(key),                    // plugin-scoped
-    set(key, value),             // auto-persisted via electron-store
-    onChanged(key, callback)
-  },
-  editor: {
-    getContent(),                // current document
-    getSelection(),              // selected text
-    insertAtCursor(text),        // requires opt-in
-    onContentChanged(callback)
-  },
-  events: {
-    on(event, handler),
-    emit(event, data)
-  },
-  exports: {
-    registerPreHook(handler),
-    registerPostHook(handler)
-  },
-  ipc: {
-    invoke(channel, ...args),
-    on(channel, handler)
-  }
-}
-```
-
-### Event Bus Events
-
-Each event has a versioned payload schema. Breaking changes increment the version suffix.
-
-```
-document:opened        → { filePath: string, tabId: string }
-document:saved         → { filePath: string, tabId: string }
-document:changed       → { tabId: string, content: string, wordCount: number }
-editor:selection-changed → { tabId: string, text: string, from: {line,ch}, to: {line,ch} }
-tab:switched           → { tabId: string, filePath: string }
-tab:closed             → { tabId: string, filePath: string }
-export:started         → { format: string, filePath: string }
-export:completed       → { format: string, filePath: string, outputPath: string }
-export:failed          → { format: string, error: string }
-plugin:loaded          → { pluginId: string, version: string }
-plugin:activated       → { pluginId: string }
-plugin:deactivated     → { pluginId: string }
-app:ready              → {}
-app:before-quit        → {}
-```
-
-### Design Rules
-
-- Built-in plugins use the same API as future third-party plugins
-- Lazy activation — sidebar panels don't load until clicked
-- Scoped settings: `plugins.<id>.<key>` in electron-store
-- Plugin commands globally unique — registry rejects duplicate command IDs at load time
-- **Plugin sandboxing**: each plugin handler is wrapped in try/catch. For CPU-intensive operations (AI inference, diff computation), plugins must delegate to main process via IPC. Handlers that block the renderer for >5s trigger a warning notification. Memory-hungry operations (GGUF inference) run in isolated child processes.
-- **Cross-plugin graceful degradation**: plugins check `context.events.hasHandler('ai:analyze')` before emitting cross-plugin requests. If no handler (AI plugin disabled), show a "this feature requires the AI plugin" prompt instead of failing silently. All cross-plugin calls have a 30s timeout with default fallback behavior.

-## 2. Writing Studio Plugin
-
-### 2A. Manuscript / Project Manager
-
-Folder-based project structure:
-
-```
-~/Manuscripts/
-  my-novel/
-    .project.json          # { title, targets, metadata }
-    01-chapter-one.md
-    02-chapter-two.md
-    characters/
-      protagonist.md
-    research/
-      world-building.md
-    .snapshots/
-      2026-04-14T10-30.json
-```
-
-`.project.json`:
-
-```json
-{
-  "title": "My Novel",
-  "type": "manuscript",
-  "target": { "words": 80000, "deadline": "2026-09-01" },
-  "chapters": [
-    { "file": "01-chapter-one.md", "title": "The Beginning", "status": "draft" }
-  ],
-  "metadata": { "author": "", "genre": "", "synopsis": "" }
-}
-```
-
-Sidebar panel shows project tree with drag-to-reorder, word counts per chapter, target progress bar. "Compile manuscript" exports all chapters as a single document.
-
-### 2B. Goal Tracking & Writing Sprints
-
-- **Status bar**: daily progress bar + sprint timer
-- **Writing sprint**: configurable duration (15/25/30/45/60 min), word count delta, WPM at end
-- **Goal tracking**: daily/weekly word goals, streak tracking, 30-day bar chart
-- **Enhanced analytics**: session tracking, readability scores, productive time-of-day heatmap
-- Data stored in `plugins.writing-studio.history` as date-keyed map
-
-### 2C. Snapshot & Versioning
-
-- `Ctrl+Alt+N` or toolbar button saves snapshot
-- Stored as JSON: `{ timestamp, content, wordCount, cursorPos, label }`
-- Snapshot panel in sidebar: Restore, Diff (side-by-side), auto-snapshot interval
-- Snapshots in `.snapshots/` inside project folder, or app data if no project
-
-### 2D. Smart Proofreading
-
-Delegates to AI plugin via event bus. Writing Studio provides:
-- Right-click context menu: "Check grammar", "Suggest alternatives", "Analyze readability"
-- Inline wavy underline decorations for issues
-- Proofread panel: issues categorized by type with Accept/Dismiss
-
-### Commands
-
-| Command | Shortcut | Action |
-|---------|----------|--------|
-| `start-sprint` | `Ctrl+Alt+S` | Start writing sprint |
-| `stop-sprint` | `Ctrl+Alt+Shift+S` | Stop sprint |
-| `take-snapshot` | `Ctrl+Alt+N` | Save snapshot |
-| `restore-last-snapshot` | `Ctrl+Alt+Z` | Restore latest snapshot |
-| `new-project` | — | Create manuscript project |
-| `compile-manuscript` | `Ctrl+Alt+E` | Export all chapters |
-| `proofread-document` | `Ctrl+Alt+G` | AI proofread |

-### Provider Architecture

-  │     ├── complete(prompt, options) → string
-  │     ├── stream(prompt, options) → AsyncIterable
-  │     └── analyze(text, type) → AnalysisResult
-  │
-  ├── Providers
-  │     ├── OllamaProvider      — localhost:11434
-  │     ├── LMStudioProvider    — localhost:1234/v1
-  │     ├── GGUFProvider         — direct llama.cpp with GPU support

-        ├── AI chat panel (sidebar)
-        ├── Document analysis
-        └── Smart commands (command palette)
-```
-
-### Provider Details
-
-**Ollama:** `GET /api/tags` for models, `POST /api/generate` and `POST /api/chat` for inference.
-
-**LMStudio:** OpenAI-compatible API at `localhost:1234/v1`. `GET /v1/models`, standard chat completion format, SSE streaming.
-
-**GGUF Direct (with GPU):**
-- Ships bundled llama.cpp binaries per platform (CUDA, Vulkan, Metal, CPU variants)
-- Auto-detects GPU: CUDA (nvidia-smi), Vulkan driver, Metal (macOS)
-- GPU layer offloading: configurable, auto-suggests based on VRAM vs model size
-- Settings: GPU backend selection, layer count, context length, thread count
-- "Keep model loaded" option for faster repeated requests
-- WASM fallback for sandboxed environments (CPU-only)
-- External binary path for advanced users with custom builds
-- **Process isolation**: llama.cpp runs as a spawned child process (not in main process). If it crashes, detected via exit handler, auto-restarted with notification. GPU memory freed on crash. App remains stable.
-- Process management: spawn in server mode on localhost ephemeral port, clean up on app quit or model unload
-
-**Cloud (Anthropic/OpenAI):**
-- API key stored encrypted via electron safeStorage
-- Token usage tracking with estimated cost
-- Rate limit awareness with request queueing and backoff
-
-### IPC Design
-
-All provider HTTP requests go through main process:
-- No CORS issues
-- API keys never in renderer
-- Main process enforces rate limiting
-- GGUF inference in isolated child process
-
-**Request/response lifecycle:**
-```
-Renderer → ipc.invoke('ai:complete') → Main → HTTP to provider → result → Renderer
-```
-
-**Streaming lifecycle with error handling:**
-```
-Renderer → ipc.invoke('ai:stream', { requestId, prompt })
-         ← Main assigns requestId, returns { requestId }
-         ← ipc.on('ai:chunk', { requestId, text }) — repeated
-         ← ipc.on('ai:done', { requestId }) — success
-         ← ipc.on('ai:error', { requestId, error }) — failure
-
-// Cancellation
-Renderer → ipc.invoke('ai:cancel', { requestId })
-         ← Main aborts HTTP request, emits 'ai:done'
-
-// Orphan cleanup: if renderer disconnects (crash/close),
-// main process detects via 'render-view-deleted' and aborts all active streams.
-// Heartbeat: if no chunk received in 30s, main emits 'ai:error' with timeout.
-```
-
-### Features
-
-1. **Inline suggestions**: ghost text after configurable delay, Tab to accept, Esc to dismiss
-2. **AI chat panel**: sidebar conversation, "Insert" / "Replace selection" buttons
-3. **Document analysis**: grammar, style, tone, with accept/reject per suggestion
-4. **Smart commands**: summarize, generate outline, find inconsistencies, translate, explain code
-
-### Privacy
-
-- Local-first: default provider is Ollama
-- No telemetry: requests go direct to provider
-- Content gating: exclude file types from AI
-- Status bar shows "AI: processing..." with cancel option
-- Cloud usage stats in settings (tokens, cost)
-
-### Cross-Plugin Integration
-
-```javascript
-// Writing Studio calls AI Plugin
-context.events.emit('ai:analyze', { text, type: 'grammar', callback });
-```
-
----
-
-## 4. Collaboration Plugin
-
-### 4A. Enhanced Git Panel
-
-Upgrades to existing git panel:
-- Remote management (add/remove remotes, push/pull)
-- Branch list and switching
-- Commit history with diff viewer (side-by-side or unified)
-- Conflict resolution UI (accept-ours/accept-theirs/per-edit)
-
-### 4B. Shared Repository Workflow
-
-1. Writer A creates project + initializes git + pushes to shared repo
-2. Writer B clones repo from within MarkdownConverter
-3. Both write on their own branches
-4. Writer A creates review request (simplified PR)
-
-Review request: changed files, word count diff, commit messages. Reviewer can approve, request changes, leave inline comments. Reviews are git branches + comments as git notes.
-
-### 4C. Comments & Annotations
-
-Inline comments stored as JSON in `.comments/` directory (git-tracked):
-```json
-{
-  "id": "uuid",
-  "file": "03-chapter-three.md",
-  "anchor": {
-    "contextBefore": "The hero looked at the horizon and said,",
-    "selectedText": "I will not go quietly into that dark night",
-    "contextAfter": "He turned to face the army alone."
-  },
-  "line": 142,
-  "text": "This dialogue feels unnatural",
-  "author": "amit",
-  "timestamp": "2026-04-14T14:30:00Z",
-  "replies": [],
-  "resolved": false
-}
-```
-
-- **Anchor-based positioning**: comments store `contextBefore`, `selectedText`, and `contextAfter` (not absolute byte offsets). On file change, re-anchor by searching for the context text. If context no longer matches, mark comment as "detached" and show a warning. Falls back to `line` number as rough position.
-- Highlighted text in editor with tooltip on hover
-- Comment panel in sidebar: all unresolved comments across files
-- Resolution workflow: add → address → reply → resolve
-- Resolved comments dim but stay visible
-
-### 4D. Change Notifications
-
-- Status bar indicator: `↓ 3 new commits`
-- Click to see changes, one-click pull
-- Conflicts trigger resolution UI
-- Push button only when local commits ahead of remote
-
-### 4E. Offline-First
-
-All writing happens locally. Git is the sync mechanism. No internet required for writing, commenting, snapshots, or sprints. Push/pull on user action or auto-sync setting.
-
-### Commands
-
-| Command | Shortcut | Action |
-|---------|----------|--------|
-| `collab:commit` | `Ctrl+Shift+G` | Commit with message |
-| `collab:push` | — | Push current branch |
-| `collab:pull` | — | Pull from remote |
-| `collab:add-comment` | `Ctrl+Alt+C` | Comment on selection |
-| `collab:next-comment` | `F8` | Next unresolved comment |
-| `collab:prev-comment` | `Shift+F8` | Previous comment |
-| `collab:create-review` | — | Create review request |
-
-### Cross-Plugin Integration
-
-```javascript
-context.events.emit('snapshot:created', { file, snapshotId });
-context.events.on('project:chapter-opened', (chapter) => { /* load comments */ });
-context.events.on('comment:added', (comment) => { /* AI could suggest fix */ });
-```
-
----
-
-## Bundle Size Impact
-
-- llama.cpp binaries: ~15MB per GPU variant. Only target platform shipped. GPU variants (CUDA/Vulkan/Metal) downloaded on demand if user enables GGUF direct loading — not bundled by default. Only CPU fallback bundled (~15MB).
-- Plugin system core: ~30KB
-- Each built-in plugin: ~50-100KB
-- Diff library (jsdiff): ~15KB
-- Total estimated increase: ~20-30MB (core), additional ~30-50MB per GPU variant (lazy download)
-
-## Testing Strategy
-
-- Plugin system: unit tests for registry, loader, context API mocking
-- Each plugin: isolated unit tests, integration tests via plugin context
-- AI provider tests: mock HTTP responses, test streaming parsing
-- Git tests: use test repository fixture
-- E2E: verify plugin loading doesn't break existing features

-# Phase 7 — Modals Design
-
-> Companion to the parent plan: `docs/superpowers/plans/2026-06-05-react-ui-redesign.md` (Phases 7+8+9+10 are sketched there at high level; this spec locks Phase 7's architecture, file map, and contracts so it can be planned task-by-task.)
-
-**Date:** 2026-06-05
-**Phase:** 7 of 10 (React + shadcn/ui UI redesign)
-**Tag (on completion):** `phase-7-modals`
-
----
-
-## 1. Goal & Non-Goals
-
-**Goal:** Add a layered modal system to the React renderer. Wire 7 modal types (SettingsSheet + 4 Export dialogs + About + Welcome + Confirm) to a single `<ModalLayer />`. Add a persisted `useSettingsStore` for user preferences. The modals are opened via the command store (Phase 6 pattern), and the modals themselves read/write settings via the new store.
-
-**Non-goals (Phase 7):**
-- Implement the actual export pipelines (PDF/DOCX/HTML/PNG generation) — those are main-process concerns, already implemented. Phase 7 only adds the renderer-side dialog UI.
-- Real plugin system — the Plugins tab is a placeholder ("Coming soon").
-- Toast notifications — Phase 8.
-- Advanced tools (Zen mode, REPL, ASCII/Table generators, Print preview) — Phase 9.
-
----
-
-## 2. Architecture
-
-### 2.1 Modal state lives in `useAppStore` (extended, not new store)
-
-`useAppStore` is already the "global UI" store (sidebar, preview, zen, paneSizes). It's the right home for modal state because:
-- It's already mounted.
-- It's already persisted (via `zustand persist` with `partialize` for pane sizes).
-- A separate `useUIStore` would be YAGNI.
-
-**Add to `AppState`:**
-- `modal: ModalState` (discriminated union — see §2.2)
-- `openModal: <K extends ModalKind>(kind: K, props?: ModalPropsFor<K>) => void`
-- `closeModal: () => void`
-
-**Persistence:** `modal` is **runtime-only**, like `userBindings` in `useCommandStore`. We add it to the `partialize` function so only the persisted fields (`sidebarVisible`, `previewVisible`, `zenMode`, `paneSizes`) are saved. The modal kind never needs to survive a reload.
-
-### 2.2 Discriminated-union modal shape
-
-```ts
-export type ModalState =
-  | { kind: null }
-  | { kind: 'export-pdf';     props: { sourcePath: string } }
-  | { kind: 'export-docx';    props: { sourcePath: string } }
-  | { kind: 'export-html';    props: { sourcePath: string } }
-  | { kind: 'export-batch';   props: { sourcePaths: string[] } }
-  | { kind: 'settings' }
-  | { kind: 'about' }
-  | { kind: 'welcome' }
-  | { kind: 'confirm';        props: ConfirmProps };
-
-export interface ConfirmProps {
-  title: string;
-  body: string;
-  confirmLabel?: string;       // default "Confirm"
-  cancelLabel?: string;        // default "Cancel"
-  destructive?: boolean;       // switches confirm button to red variant
-  onConfirm: () => void | Promise<void>;
-  onCancel?: () => void;
-}
-```
-
-**Why a discriminated union:** every component that opens a modal must pass the right `props` shape for the `kind` — TypeScript catches mismatches at compile time. A generic `{ open: boolean, type: string }` shape would defer the error to runtime.
-
-### 2.3 Single `<ModalLayer />`
-
-Mounted at the bottom of `App.tsx`. Reads `modal.kind` from `useAppStore`, renders the matching component (or `null`). Each child modal calls `closeModal()` on dismiss.
-
-```tsx
-// src/renderer/components/modals/ModalLayer.tsx (sketch)
-export function ModalLayer() {
-  const modal = useAppStore((s) => s.modal);
-  switch (modal.kind) {
-    case null: return null;
-    case 'export-pdf':   return <ExportPdfDialog {...modal.props} />;
-    // ... etc
-  }
-}
-```
-
-`<ModalLayer />` ensures only one modal is visible at a time (the store only holds one). This is correct for v1 — no need for stacking/replacement transitions in Phase 7.
-
-### 2.4 Settings store (new, separate)
-
-A new `useSettingsStore` for user preferences. **Why separate from `useAppStore`:** settings is a different lifecycle. `useAppStore` is "current view configuration"; `useSettingsStore` is "user preferences that survive across sessions and are read by many features". Same precedent as `useFileStore` (file tree state) being separate from `useAppStore` (UI chrome state).
-
-**Persistence:** `zustand persist` with `partialize` to serialize only the leaf settings (matching the pattern in `useFileStore` and `useCommandStore`).
-
-```ts
-interface SettingsState {
-  // Editor
-  fontSize: number;            // 12-20, default 14
-  tabSize: number;             // 2 | 4 | 8, default 4
-  lineNumbers: boolean;        // default true
-  wordWrap: boolean;           // default true
-  minimap: boolean;            // default true
-  // Theme
-  theme: 'light' | 'dark' | 'auto';  // default 'auto'
-  accentColor: 'brand' | 'blue' | 'green' | 'purple' | 'orange';  // default 'brand'
-  fontFamily: 'system' | 'jetbrains' | 'fira';  // default 'system'
-  // Export
-  pdfFormat: 'letter' | 'a4' | 'legal';  // default 'a4'
-  pdfMargins: 'normal' | 'narrow' | 'wide';  // default 'normal'
-  pdfEmbedFonts: boolean;       // default true
-  docxTemplate: 'standard' | 'minimal' | 'modern';  // default 'standard'
-  htmlHighlightStyle: 'github' | 'monokai' | 'nord' | 'none';  // default 'github'
-  // ASCII table formatting — applies to all 3 single-file export formats
-  renderTablesAsAscii: boolean;  // default false
-  // First-launch / Welcome
-  welcomeDismissed: boolean;    // default false
-  // Actions
-  setSetting: <K extends keyof Omit<SettingsState, ...>>(...);
-  resetToDefaults: () => void;
-}
-```
-
-**Template-based exports** (per user request): `docxTemplate` is one of `'standard' | 'minimal' | 'modern'`. The export dialog shows a Select with the available templates. The IPC layer (`ipc.export.docx`) already accepts a `template` field; Phase 7 just exposes it. The main process maps these template names to actual `.docx` template files bundled with the app.
-
-**ASCII table formatting** (per user request): `renderTablesAsAscii` is a toggle in the Settings sheet (Export tab) and in each of the 3 single-file export dialogs as an inline checkbox override. When true, the markdown AST's table nodes are converted to fixed-width monospace text (using a small `lib/ascii-table.ts` helper) *before* the export pipeline sees them. The preview pane is unaffected — this is export-time only.
-
-### 2.5 WelcomeDialog trigger logic
-
-A small `useEffect` in `App.tsx`:
-```ts
-useEffect(() => {
-  if (!useSettingsStore.getState().welcomeDismissed) {
-    useAppStore.getState().openModal('welcome');
-  }
-}, []);  // run once on mount
-```
-
-The Help menu registers a `help.welcome` command that simply calls `openModal('welcome')` — does NOT reset the `welcomeDismissed` flag. (Decision in §2.4 of the brainstorming.)
-
-### 2.6 Commands trigger modals
-
-The command store (Phase 6) gets new commands. Registered in `src/renderer/lib/commands/register-menu-commands.ts`:
-
-| Command ID       | Handler                                              |
-|------------------|------------------------------------------------------|
-| `file.exportPdf`     | `openModal('export-pdf', { sourcePath: activePath })`  |
-| `file.exportDocx`    | `openModal('export-docx', { sourcePath: activePath })` |
-| `file.exportHtml`    | `openModal('export-html', { sourcePath: activePath })` |
-| `file.exportBatch`   | `openModal('export-batch', { sourcePaths: openFiles })` |
-| `settings.open`      | `openModal('settings')`                                  |
-| `help.welcome`       | `openModal('welcome')`                                   |
-| `help.about`         | `openModal('about')`                                     |
-| `file.confirmClose`  | opens confirm dialog before closing a dirty tab        |
-| `app.quit`           | opens confirm if dirty tabs exist, else quits          |
-
-`settings.open` and `help.about` also get buttons in `AppHeader` (already partly done in Phase 6 — we just add new icons and wire to the new commands).

-
-### 3.3 Stores
-
-- **Modify** `src/renderer/stores/app-store.ts` — add `modal` + `openModal` + `closeModal`; update `partialize` to exclude `modal`
-- **Create** `src/renderer/stores/settings-store.ts` — new
-
-### 3.4 Lib
-
-- **Create** `src/renderer/lib/validators.ts` — zod schemas:
-  - `settingsSchema` (whole settings object)
-  - `exportPdfSchema` (format, margins, embedFonts, renderTablesAsAscii)
-  - `exportDocxSchema` (template, renderTablesAsAscii)
-  - `exportHtmlSchema` (standalone, highlightStyle, renderTablesAsAscii)
-  - `exportBatchSchema` (format, concurrency, file list)
-  - `confirmPropsSchema` (for the confirm dialog)
-- **Create** `src/renderer/lib/ascii-table.ts` — `toAsciiTable(rows: string[][]): string` (the small helper that converts a 2D string array to a fixed-width ASCII table)
-- **Create** `src/renderer/lib/modal-triggers.ts` — small helpers: `useWelcomeTrigger()`, `useQuitGuard()`
-
-### 3.5 Modified files
-
-- **Modify** `src/renderer/App.tsx` — mount `<ModalLayer />` at the bottom; add the `useWelcomeTrigger` `useEffect` for first-launch
-- **Modify** `src/renderer/lib/commands/register-menu-commands.ts` — add the 9 new commands (4 export + settings + welcome + about + confirmClose + quit)
-- **Modify** `src/renderer/components/layout/AppHeader.tsx` — add Settings (gear) and About (info) icon buttons that dispatch the new commands
-- **Modify** `src/main.js` (verify) — no changes expected; menu items already wire to `menu:action` channels that flow through `useBridgeNativeMenu`. If any new menu items need IPC channels, add them in the main process mirror.
-
-### 3.6 Tests
-
-**Unit (`tests/unit/`):**
-- `stores/settings-store.test.ts` (5-6 tests: defaults, setSetting, resetToDefaults, persistence/partialize)
-- `stores/app-store.test.ts` extended (3 tests: openModal sets state, closeModal clears, only one modal at a time)
-- `lib/validators.test.ts` (3 tests: each schema rejects bad input)
-- `lib/ascii-table.test.ts` (3 tests: simple table, alignment, empty input)
-
-**Component (`tests/component/modals/`):**
-- `ExportPdfDialog.test.tsx` (4 tests: renders with default settings, submit calls ipc.export.pdf with merged opts, error renders inline, ascii-table toggle flows through)
-- `ExportDocxDialog.test.tsx` (3 tests: renders, submit includes template, ascii-table toggle)
-- `ExportHtmlDialog.test.tsx` (3 tests: renders, highlight style select, ascii-table toggle)
-- `ExportBatchDialog.test.tsx` (3 tests: renders file list, format selector, concurrency)
-- `SettingsSheet.test.tsx` (6 tests: renders 5 tabs, each tab shows correct fields, settings change persists)
-- `AboutDialog.test.tsx` (2 tests: renders version, links open external)
-- `WelcomeDialog.test.tsx` (3 tests: renders, dismiss sets welcomeDismissed, "don't show again" checked)
-- `ConfirmDialog.test.tsx` (3 tests: confirm calls onConfirm and closes, cancel calls closeModal, destructive variant)
-- `ModalLayer.test.tsx` (3 integration tests: null kind renders nothing, switching kinds replaces modal, modal unmounts on close)
-
-**Integration (`tests/integration/`):**
-- `phase7-modals-smoke.test.tsx` (4 tests: dispatch command opens modal, command store + settings store + IPC all wired, app.tsx mount triggers welcome on first launch, modal layer end-to-end)

-
-## 4. Data Flow
-
-### 4.1 Open a modal
-```ts
-// From any command handler in register-menu-commands.ts:
-useAppStore.getState().openModal('export-pdf', { sourcePath: activePath });
-```
-
-### 4.2 The dialog reads source
-```ts
-// ExportPdfDialog.tsx
-const { source, path } = useExportSource();
-if (!source) return <EmptySourceFallback />;
-```
-
-`useExportSource` is a small hook that:
-1. Reads `useFileStore.activeTabId` + `useEditorStore.buffers`
-2. If no active buffer, prompts the user to open a file (uses confirm dialog)
-3. Returns `{ source: string, path: string } | null`
-
-### 4.3 Settings change
-```ts
-// EditorSettings.tsx — switches/inputs call setSetting
-const [fontSize, setFontSize] = useSettingsStore(s => [s.fontSize, s.setSetting]);
-// or
-setSetting('fontSize', 16);
-```
-
-Editor and preview subscribe to specific slices. The `useTheme` hook from `next-themes` is augmented to read `theme: 'light' | 'dark' | 'auto'` from `useSettingsStore` (replacing the standalone next-themes default).
-
-### 4.4 Export flow
-```ts
-// ExportPdfDialog on submit:
-const settings = useSettingsStore.getState();
-const result = await ipc.export.pdf({
-  inputPath: path,
-  outputPath: chosenOutputPath,
-  format: dialogFormat ?? settings.pdfFormat,
-  margins: MARGIN_PRESETS[dialogMargins ?? settings.pdfMargins],
-  embedFonts: dialogEmbed ?? settings.pdfEmbedFonts,
-  renderTablesAsAscii: dialogAscii ?? settings.renderTablesAsAscii,
-});
-if (!result.ok) setError(result.error.message);
-else { closeModal(); /* toast in Phase 8 */ }
-```
-
-The dialog-level overrides fall through to settings defaults when not explicitly chosen.
-
-### 4.5 ASCII table transformation
-The transformation happens in the **renderer** (pre-IPC), so the main process doesn't need to know about ASCII mode:
-```ts
-// In ExportPdfDialog before submitting:
-const finalSource = renderTablesAsAscii
-  ? applyAsciiTransform(source)   // walks AST, replaces <table> blocks
-  : source;
-```
-`applyAsciiTransform` is a small function (10-20 lines) that:
-1. Parses markdown source for `|...|` table syntax via a small regex
-2. Replaces each table block with a fenced code block containing the ASCII table
-3. Returns the modified source
-
-(No AST walker needed — markdown tables are line-based and a regex per line + simple width calc is sufficient.)
-
-### 4.6 DOCX template selection
-The dialog shows a Select with 3 options (standard, minimal, modern). The main process maps these names to bundled `.docx` template files. The IPC contract is unchanged — `DocxOptions.template: string` was already defined in `types/ipc.ts` during Phase 1.
-
-### 4.7 Confirm flow
-```ts
-// In a command handler:
-const activeTab = ...;
-if (activeTab?.dirty) {
-  useAppStore.getState().openModal('confirm', {
-    title: 'Discard unsaved changes?',
-    body: `"${activeTab.title}" has unsaved changes. Close without saving?`,
-    confirmLabel: 'Discard',
-    destructive: true,
-    onConfirm: () => doCloseTab(),
-  });
-} else {
-  doCloseTab();
-}
-```
-
-### 4.8 Welcome first-launch
-`useEffect` in `App.tsx` (run once on mount) checks `welcomeDismissed` from `useSettingsStore`. If false, calls `openModal('welcome')`. The Welcome dialog has a "Don't show again" checkbox that sets `welcomeDismissed: true` and closes.
-
----
-
-## 5. Error Handling
-
-- **IPC errors in export dialogs:** inline error banner below the submit button. `IpcResult<T>` discriminated union makes this easy. Banner shows `result.error.message` and a "Try again" button that re-submits.
-- **Settings validation:** zod schemas in `validators.ts`. Each form field shows `aria-invalid` + red border on error. Form-level errors via react-hook-form's `formState.errors`.
-- **Confirm dialog cancel:** just calls `closeModal()`. No state mutation. Optional `onCancel` callback for "remember my choice" patterns (not used in Phase 7).
-- **Welcome "don't show again":** persists `welcomeDismissed: true`. Help menu can re-open Welcome (without resetting the flag).
-- **Settings corruption on load (bad localStorage data):** `useSettingsStore` is built with a `partialize` that also acts as a whitelist — only known fields are deserialized. Unknown fields are dropped. If a persisted value fails zod validation, fall back to defaults (logged as a warning).
-
----
-
-## 6. Testing Strategy
-
-TDD per the established pattern (Phases 1-6). Every component test:
-- Renders with empty/default state
-- One happy-path interaction (form submit, button click)
-- One error/edge case (validation fail, IPC error, cancel)
-
-Store tests focus on pure logic (state transitions, persistence, partialize). Settings store test specifically verifies:
-- Defaults match schema
-- `setSetting` works for leaf keys
-- `resetToDefaults` clears to initial state
-- Persisted payload (from `partialize`) contains exactly the leaf fields
-- Hydration from a partial/corrupt payload doesn't throw
-
-Component tests use `render` + `userEvent`, mock `window.electronAPI` for IPC.
-
-ModalLayer integration test verifies:
-1. Mounting with `kind: null` renders nothing (query container, expect empty)
-2. Mounting with `kind: 'about'` renders `<AboutDialog>` (aria-label match)
-3. Switching from `kind: 'about'` to `kind: 'settings'` unmounts About, mounts Settings (verified by role/aria-label transitions)
-4. Confirm dialog calls `onConfirm` and `closeModal` on success
-
----
-
-## 7. Risks & Open Questions
-
-**Risks:**
-- **Form library complexity.** react-hook-form + zod is powerful but adds learning curve. Mitigation: a single shared `<SettingsForm>` wrapper reduces cognitive load; export dialogs use simple `useState` (no need for the full form infra).
-- **shadcn Dialog animation jank with our motion presets.** Radix Dialog has its own `data-state` attributes for open/closed. We compose with our `modalPop` preset via `forceMount` + Motion. Need to verify no double-animation.
-- **Settings store hydration race.** If a component reads a setting on first render before hydration completes, it gets the default. For Phase 7 this is fine — defaults are sensible.
-
-**Open questions (deferrable):**
-- Should the "ascii table" output include alignment row separators (`+---+---+`) or just be a `| a | b |`-style table? → Decision: use the `|---|` separator form (more compact, common in plain-text email).
-- Should ExportBatchDialog be a Sheet (queue progress) or a Dialog (form)? → Decision: Dialog with a form; progress is shown inline (not a streaming queue). Phase 9 could revisit.
-- Should `welcomeDismissed` be per-user-account or per-install? → Per-install (localStorage). No multi-user concept in v1.
-
----
-
-## 8. Out of Scope (deferred to later phases)
-
-- Phase 8: Toast notifications on export success/failure (the dialog's inline error is v1; toasts are a follow-up).
-- Phase 9: ASCII art generator (figlet) is separate from ASCII table rendering. This spec is about table formatting.
-- Phase 9: Word export uses a `.docx` template *generation* step (WordExportDialog), not the IPC `ipc.export.docx` path. Distinct.
-- Phase 10: Delete legacy `src/print-preview.js`, `src/wordTemplateExporter.js`, etc.
-
----
-
-## 9. Success Criteria
-
-Phase 7 is complete when:
-- All listed shadcn primitives exist in `src/renderer/components/ui/` with tests
-- `useSettingsStore` is implemented, tested, and persisted
-- `useAppStore` extended with `modal` discriminated union and tested
-- All 7 modal components implemented, tested, and accessible (aria-labels, keyboard nav)
-- 4 export dialogs (PDF/DOCX/HTML/Batch) all submit through the command store and call IPC correctly
-- `ModalLayer` mounted in `App.tsx` and integrated with command triggers
-- Welcome dialog shows on first launch, dismissible, re-openable from Help menu
-- Confirm dialog used by quit-with-dirty and close-with-dirty flows
-- ASCII table rendering works (toggle in settings, override in export dialogs)
-- DOCX template picker in ExportDocxDialog submits the correct `template` field
-- `npx vite build` succeeds, `npx vitest run` shows **all tests green** (target: +50 new tests, total ~220)
-- Branch tagged `phase-7-modals` and pushed to origin

-# Phase 8 — Toasts Design
-
-> Companion to the parent plan: `docs/superpowers/plans/2026-06-05-react-ui-redesign.md` (Phases 8+9+10 are sketched at high level; this spec locks Phase 8's architecture, file map, and contracts so it can be planned task-by-task.)
-
-**Date:** 2026-06-05
-**Phase:** 8 of 10 (React + shadcn/ui UI redesign)
-**Tag (on completion):** `phase-8-toasts`
-
----
-
-## 1. Goal & Non-Goals
-
-**Goal:** Add a toast notification layer to the React renderer using sonner (already installed). Surface user-initiated async action results (file save, file/folder open, exports) as transient toasts in the bottom-right of the window. The error banner pattern in export dialogs stays — toasts are a complementary global channel.
-
-**Non-goals (Phase 8):**
-- Undo/redo support (Phase 9)
-- Custom toast actions/buttons (Phase 9, if needed)
-- Persistent notification history
-- Toast queueing/throttling for rapid-fire events
-- Replacing inline error banners (they stay as per-dialog context)
-
-**Scope decision:** Toast on user-initiated actions only. Skip silent background operations (loadChildren, etc.) to avoid noise. 4 wire points total: save (success+error), open file/folder (error only), 4 export dialogs (success+error).
-
----
-
-## 2. Architecture
-
-### 2.1 Toast helpers in `lib/toast.ts`
-
-A thin typed layer over sonner. The helpers exist to:
-- Give us a single import surface (instead of scattering `import { toast } from 'sonner'` across the codebase)
-- Provide a place to add brand colors, formatting, or analytics later without touching call sites
-- Make mocking easier in tests (one module to mock)
-
-```ts
-// src/renderer/lib/toast.ts (sketch)
-import { toast as sonnerToast } from 'sonner';
-
-export const toast = {
-  success: (message: string) => sonnerToast.success(message),
-  error: (message: string) => sonnerToast.error(message),
-  info: (message: string) => sonnerToast.info(message),
-  warning: (message: string) => sonnerToast.warning(message),
-  promise: <T>(
-    promise: Promise<T>,
-    msgs: { loading: string; success: string | ((data: T) => string); error: string | ((err: unknown) => string) }
-  ) => sonnerToast.promise(promise, msgs),
-  dismiss: (id?: string | number) => sonnerToast.dismiss(id),
-};
-```
-
-### 2.2 `<Toaster />` mounted in App.tsx
-
-A canonical shadcn Toaster wrapper (manual paste per memory `shadcn-cli-blocked-manual-primitives`). Mounts alongside `<ModalLayer />`:
-
-```tsx
-// src/renderer/App.tsx (sketch)
-import { Toaster } from '@/components/ui/sonner';
-
-function App() {
-  useWelcomeTrigger();
-  return (
-    <>
-      <AppShell />
-      <ModalLayer />
-      <Toaster />
-    </>
-  );
-}
-```
-
-The Toaster uses sonner's `<Toaster />` component with:
-- `theme={resolvedTheme}` from `useTheme()` (so toasts match the user's light/dark preference)
-- `richColors` for semantic success/error/info/warning colors
-- `position="bottom-right"` (sonner default; explicit for clarity)
-- `closeButton` (so users can dismiss)
-
-### 2.3 Inline wiring at 4 wire points
-
-**Pattern choice — inline in stores/dialogs, NOT middleware.** Matches the Phase 7 precedent of inline error banners in export dialogs. Middleware would be DRY but harder to debug and harder to control granularity (we want errors on save, but NOT on silent loadChildren).
-
-**Wire points:**
-
-1. **`useFileStore.saveActiveBuffer`** — wrap the existing logic:
-   ```ts
-   saveActiveBuffer: async () => {
-     // ... existing logic to get buffer ...
-     const writeResult = await ipc.file.write(activeTabId, buffer.content);
-     if (!writeResult.ok) {
-       toast.error(`Failed to save: ${writeResult.error.message}`);
-       return false;
-     }
-     // ... existing markSaved/markTabClean ...
-     toast.success(`Saved ${title}`);
-     return true;
-   }
-   ```
-
-2. **`useFileStore.openFile`** — error only:
-   ```ts
-   openFile: async (filePath) => {
-     // ... existing logic to check existing tab ...
-     const result = await ipc.file.read(filePath);
-     if (!result.ok) {
-       toast.error(`Failed to open file: ${result.error.message}`);
-       return;
-     }
-     // ... existing logic ...
-   }
-   ```
-
-3. **`useFileStore.openFolder`** — error only:
-   ```ts
-   openFolder: async (path) => {
-     const result = await ipc.file.list(path);
-     if (!result.ok) {
-       toast.error(`Failed to open folder: ${result.error.message}`);
-       return;
-     }
-     // ... existing logic ...
-   }
-   ```
-
-4. **4 export dialogs** — both success and error (error complements the inline banner):
-   ```ts
-   if (!result.ok) {
-     toast.error(`Export failed: ${result.error.message}`);
-     setError(result.error.message);
-     setSubmitting(false);

-## 3. File Map
-
-### 3.1 Created files
-
-- `src/renderer/lib/toast.ts` — typed wrappers (re-export of sonner with our naming)
-- `src/renderer/components/ui/sonner.tsx` — canonical shadcn Toaster wrapper (manual paste)
-- `tests/unit/lib/toast.test.ts` — ~5 unit tests
-- `tests/component/ui/sonner.test.tsx` — 1 smoke test
-- `tests/integration/phase8-toasts-smoke.test.tsx` — ~4 integration tests
-
-### 3.2 Modified files
-
-- `src/renderer/App.tsx` — mount `<Toaster />` alongside `<ModalLayer />`
-- `src/renderer/stores/file-store.ts` — add 3 toast calls (save, openFile, openFolder)
-- `src/renderer/components/modals/ExportPdfDialog.tsx` — toast on submit result
-- `src/renderer/components/modals/ExportDocxDialog.tsx` — toast on submit result
-- `src/renderer/components/modals/ExportHtmlDialog.tsx` — toast on submit result
-- `src/renderer/components/modals/ExportBatchDialog.tsx` — toast on submit result
-
----
-
-## 4. Data Flow
-
-User action → store action OR export dialog submit → IPC call → result →
-- if error: `toast.error(message)` → sonner renders in bottom-right portal
-- if success: `toast.success(message)` → sonner renders
-- inline error banner in dialog stays as per-dialog context (NOT removed)
-
-Theme comes from `useTheme()` in the Toaster component, not from individual toasts. The Toaster is mounted once at the app level.
-
-For the 4 export dialogs: the existing inline error banner stays (it's contextual to the dialog), AND a toast is fired. This gives the user both immediate context (in the dialog) and persistent notification (toast in corner).
-
-For file save: ONLY a toast (no inline error UI in the editor pane — keeps the editor clean). Errors still show the toast.
-
----
-
-## 5. Error Handling
-
-- **Toast helpers never throw.** They are thin re-exports of sonner, which handles its own error cases (e.g., render failures, missing portal target).
-- **In tests**, the `toast` module is mocked so calls don't render real toasts. Mock signature: `vi.mock('@/lib/toast', () => ({ toast: { success: vi.fn(), error: vi.fn(), ... } }))`.
-- **Theme fallback:** If `useTheme()` is loading or `resolvedTheme` is undefined, Toaster uses `'system'` as a fallback (sonner's default behavior).
-- **Sonner missing:** If for some reason sonner fails to load, the toast calls become no-ops. The user still sees inline error banners in the export dialogs.
-- **Inline error banners stay.** They are not replaced by toasts — they complement them.
-
----
-
-## 6. Testing Strategy
-
-### 6.1 Unit tests (`tests/unit/lib/toast.test.ts`)
-
-5 tests:
-- `toast.success` calls sonner `toast.success` with the message
-- `toast.error` calls sonner `toast.error` with the message
-- `toast.info` calls sonner `toast.info`
-- `toast.warning` calls sonner `toast.warning`
-- `toast.promise` forwards the promise and messages to sonner
-
-All tests mock the sonner module and verify the forwarded call.
-
-### 6.2 Component test (`tests/component/ui/sonner.test.tsx`)
-
-1 smoke test: `<Toaster />` renders without crashing inside a ThemeProvider.
-
-### 6.3 Integration test (`tests/integration/phase8-toasts-smoke.test.tsx`)
-
-~4 tests:
-- Saving a file → `toast.success` called with `"Saved test.md"`
-- Opening a non-existent file (ipc returns error) → `toast.error` called with file path in message
-- Export success (ipc returns ok) → `toast.success` called + dialog closes
-- Export failure (ipc returns error) → `toast.error` called + inline banner shown + dialog stays open
-
-TDD throughout. Mocks for `ipc.*` and `lib/toast`.
-
-### 6.4 Existing tests must still pass
-
-- All 243 tests from Phase 7 must remain green
-- Export dialog tests will need updates to verify the new toast calls (the dialog tests currently check for inline banner; they should ALSO verify the toast call)
-
----
-
-## 7. Risks & Open Questions
-
-**Risks:**
-- **Sonner theme switching:** If `useTheme()` returns `'system'` and the OS preference changes mid-session, sonner will re-render. This is the correct behavior; just confirm in test.
-- **Toast spam:** If user holds Cmd+S, the save could fire many times. Sonner deduplicates by default for similar messages? → Decision: rely on sonner's default behavior. If spam becomes an issue, add a `toast.dismiss()` debounce in v2.
-
-**Open questions (deferrable):**
-- Should we add a custom toast for "undo last close" (Phase 9's undo feature)? → Decision: out of scope for Phase 8. Phase 9 will handle undo toasts.
-- Should the export dialog inline banner be removed once toasts are wired? → Decision: NO — keep both. The inline banner is contextual to the dialog; the toast is global. They serve different purposes.
-
----
-
-## 8. Out of Scope (deferred to later phases)
-
-- Phase 9: Undo toasts ("Tab closed — Undo" with action button)
-- Phase 9: Long-running operation progress toasts (e.g., batch export queue)
-- Phase 9: Custom toast variants for advanced tools (ASCII generator, table generator)
-- Phase 10: Cleanup of inline error banners (will evaluate in Phase 10 if redundant)
-
----
-
-## 9. Success Criteria
-
-Phase 8 is complete when:
-- `lib/toast.ts` exists with typed wrappers
-- `<Toaster />` is mounted in `App.tsx` and renders toasts
-- `useFileStore.saveActiveBuffer` calls `toast.success`/`toast.error` on result
-- `useFileStore.openFile` calls `toast.error` on failure
-- `useFileStore.openFolder` calls `toast.error` on failure
-- 4 export dialogs call `toast.success`/`toast.error` on result
-- All tests pass: ~+10 new tests, total ~253
-- `npx vite build` succeeds
-- Branch tagged `phase-8-toasts` and pushed to origin

-# Phase 9 — Advanced Tools Design
-
-> Companion to the parent plan: `docs/superpowers/plans/2026-06-05-react-ui-redesign.md` (Phase 9 is sketched at high level; this spec locks architecture, file map, and contracts so it can be planned task-by-task.)
-
-**Date:** 2026-06-05
-**Phase:** 9 of 10 (React + shadcn/ui UI redesign)
-**Tag (on completion):** `phase-9-advanced-tools`
-
----
-
-## 1. Goal & Non-Goals
-
-**Goal:** Add 10 advanced tools to the React renderer. Group 1: Standalone dialogs (ASCII generator, Table generator, Word export, Find-in-files). Group 2: Global overlays (Zen mode, REPL, Print preview). Group 3: Editor/sidebar integrations (Minimap, Breadcrumbs-with-symbols, Git status). All triggered via the Phase 6 command store.
-
-**Non-goals (Phase 9):**
-- True undo/redo stack (still not in scope)
-- Snippet/template library
-- Custom REPL with full JS eval (we chose markdown snippet preview for safety)
-- Custom diff/merge UI (just shows git status, no in-app diffing)
-- Plug-in extensions
-- Multi-cursor editing
-- LSP / language server integration
-
-**Decision summary (from brainstorming):**
-- REPL = **markdown snippet preview** (no JS eval — safe in renderer)
-- Word export = **`.docx` via `docx` lib in renderer**, with both Standard and Custom .dotx template modes
-- Find-in-files = **recursive search with result navigation** (new IPC, regex support)
-
----
-
-## 2. Architecture
-
-### 2.1 Three mount strategies
-
-| Category | Mount | Examples |
-|---|---|---|
-| **Dialogs** | `<ModalLayer />` (Phase 7 pattern) | ASCII gen, Table gen, Word export, Find-in-files |
-| **Global overlays** | Top-level in `App.tsx` (like `<Toaster />`) | Zen mode, REPL panel, Print preview |
-| **Editor/sidebar integrations** | Extend existing components | Minimap, Breadcrumbs, Git status |
-
-The ModalLayer is the dispatcher for dialogs. The global overlays are mounted directly in `App.tsx` because they need to participate in the top-level layout (full-window, or pinned to the bottom).
-
-### 2.2 ModalState union extension
-
-The Phase 7 `ModalState` discriminated union (9 kinds) gets 4 new kinds for the new dialogs:
-
-```ts
-export type ModalState =
-  | { kind: null }
-  | { kind: 'export-pdf'; props: { sourcePath: string } }
-  | { kind: 'export-docx'; props: { sourcePath: string } }
-  | { kind: 'export-html'; props: { sourcePath: string } }
-  | { kind: 'export-batch'; props: { sourcePaths: string[] } }
-  | { kind: 'export-word'; props: { sourcePath: string } }   // NEW
-  | { kind: 'ascii-generator' }                                  // NEW
-  | { kind: 'table-generator' }                                  // NEW
-  | { kind: 'find-in-files' }                                    // NEW
-  | { kind: 'settings' }
-  | { kind: 'about' }
-  | { kind: 'welcome' }
-  | { kind: 'confirm'; props: ConfirmProps };
-```
-
-Three of the four new kinds (ascii, table, find-in-files) take no props — they read from the active buffer via `useExportSource` (for ascii/table) or from `useFileStore.rootPath` (for find-in-files). `export-word` takes `sourcePath` like the other export dialogs.
-
-### 2.3 New commands in command store
-
-| Command ID | Trigger | Opens |
-|---|---|---|
-| `tools.ascii` | new | `AsciiGeneratorDialog` |
-| `tools.table` | new | `TableGeneratorDialog` |
-| `tools.exportWord` | new | `WordExportDialog` |
-| `tools.findInFiles` | new | `FindInFilesDialog` |
-| `tools.repl` | new | toggles REPL panel |
-| `view.zenMode` | existing (Phase 6) | toggles Zen mode overlay |
-| `file.print` | new | opens `PrintPreview` overlay |
-| `git.refresh` | new | re-fetches git status |
-
-All registered in `src/renderer/lib/commands/register-menu-commands.ts`.
-
-### 2.4 New IPC surface
-
-```ts
-// src/renderer/lib/ipc.ts (additions)
-ipc.file.search({ rootPath, query, isRegex, caseSensitive }: {
-  rootPath: string;
-  query: string;
-  isRegex: boolean;
-  caseSensitive: boolean;
-}): Promise<IpcResult<Array<{ filePath: string; line: number; content: string }>>>;
-
-ipc.file.gitStatus({ rootPath }: { rootPath: string }): Promise<IpcResult<Array<{ filePath: string; status: 'modified' | 'added' | 'deleted' | 'untracked' }>>>;
-
-ipc.file.print({ html }: { html: string }): Promise<IpcResult<void>>;
-
-ipc.file.writeBuffer({ path, buffer }: { path: string; buffer: Uint8Array }): Promise<IpcResult<void>>;
-```
-
-The main process counterparts are added to `src/main.js` (or a new `src/main/files-search.js`, etc.). For Phase 9, the spec covers the renderer-side design; main-process IPC handlers are assumed to follow the same `ipcMain.handle` pattern as the existing handlers.
-
-### 2.5 Settings additions (`useSettingsStore`)
-
-```ts
-// zod schema additions:
-docxCustomTemplatePath: z.string().nullable().default(null),  // path to user .dotx file
-replOpen: z.boolean().default(false),                         // REPL panel visibility
-breadcrumbSymbols: z.boolean().default(true),                  // breadcrumbs show code symbols
-// minimap already exists from Phase 7 (useSettingsStore.minimap: z.boolean().default(true))
-```
-
-The `minimap` setting from Phase 7 is now wired (not just stored).
-

-
----
-
-## 4. Data Flow
-
-### 4.1 Word export (most complex)
-
-1. User triggers `tools.exportWord` → `registerMenuCommands` opens the export-word modal via `useAppStore.openModal('export-word', { sourcePath: activeTabId })`
-2. **Wait** — we need a new modal kind `export-word` in the `ModalState` union. Add it.
-3. `WordExportDialog` (mounted by ModalLayer) shows:
-   - Template select: "Standard (bundled)" or "Custom .dotx (your file)" — pre-populated with `useSettingsStore.docxCustomTemplatePath`
-   - "Choose custom template..." button (file picker, saves to settings)
-   - Options: embed images (checkbox), include front matter (checkbox)
-   - Preview area: shows the generated docx structure (sizes, table of contents)
-4. On submit:
-   - Renderer calls `lib/docx-export.ts#generateDocx(source, templatePath, options)` which uses the `docx` lib
-   - The lib takes a `Document` AST and produces a Blob
-   - ASCII tables are converted to monospace `<w:r>` runs (using `applyAsciiTransform` from Phase 7)
-   - Images are extracted from markdown and embedded as base64
-   - If a custom .dotx path is set, the renderer reads it via `ipc.file.read` and applies its styles (via `docx` lib's style support)
-   - User picks output path via `ipc.app.showSaveDialog`
-   - Writes Blob via `ipc.file.writeBuffer` (new)
-   - Toast success/failure
-
-### 4.2 Find-in-files
-
-1. User triggers `tools.findInFiles` → ModalLayer opens `FindInFilesDialog`
-2. User types query, picks regex/literal, case-sensitive toggle
-3. On submit: `ipc.file.search({ rootPath: useFileStore.rootPath, query, isRegex, caseSensitive })`
-4. Backend walks the disk recursively, applies regex/literal match, returns `Array<{ filePath, line, content }>`
-5. Dialog shows result list (file:line:content, clickable)
-6. Click a result:
-   - `useFileStore.openFile(filePath)` if not already open
-   - Set the cursor in the editor to the matched line
-7. Close the dialog
-
-### 4.3 REPL (markdown snippet preview)
-
-1. User triggers `tools.repl` → toggles `useSettingsStore.replOpen` (or a new dedicated `useReplStore`)
-2. `ReplPanel` (mounted in App.tsx) is visible when `replOpen === true`
-3. The panel has:
-   - Top half: textarea (user types/pastes markdown)
-   - Bottom half: rendered preview (uses `lib/markdown.ts` from Phase 1 + DOMPurify)
-4. Updates are debounced (300ms) for the preview
-5. Pure renderer-side, no IPC
-
-### 4.4 Zen mode
-
-1. User triggers `view.zenMode` → toggles `useSettingsStore.zenMode`
-2. `AppShell` reads `zenMode` from store; when true, hides all chrome (header, tabs, toolbar, breadcrumb, status bar, sidebar)
-3. Editor goes fullscreen
-4. Pressing Esc exits zen mode (keydown listener in `use-zen-mode` hook)
-
-### 4.5 Print preview
-
-1. User triggers `file.print` → opens `PrintPreview` (full-window overlay)
-2. The preview renders the current buffer's content as it would appear in print
-3. Two buttons: "Print" (calls `ipc.file.print({ html })` which opens native print dialog) and "Close"
-
-### 4.6 Minimap
-
-1. `useSettingsStore.minimap` (existing setting) is read by `CodeMirrorEditor`
-2. When true, the editor's extension includes `@replit/codemirror-minimap` (or a simpler custom implementation)
-3. The minimap shows a shrunk version of the document on the right side of the editor
-4. Toggling the setting adds/removes the extension dynamically
-
-### 4.7 Breadcrumbs-with-symbols
-
-1. The current `Breadcrumb` shows the file path. Extend it to also show markdown symbols (headings, code blocks)
-2. Use a simple AST walk of the current buffer to extract heading levels
-3. Show as a path-like navigation: `file.md > H1: Title > H2: Section > #line`
-4. The `useSettingsStore.breadcrumbSymbols` toggle (default true) controls whether symbols are shown
-
-### 4.8 Git status
-
-1. On sidebar Git tab open, fetch `ipc.file.gitStatus({ rootPath: useFileStore.rootPath })`
-2. The main process runs `git status --porcelain` (or equivalent) and returns the list
-3. Show file list with status badges (M, A, D, ?)
-4. Click a file opens it via `useFileStore.openFile`
-5. `git.refresh` re-fetches
-
----
-
-## 5. Error Handling
-
-- **Word export failures:** `lib/docx-export.ts` catches `docx` lib errors → toast.error
-- **Word export missing .dotx:** if custom template path is set but file doesn't exist, show inline banner in the dialog
-- **Find-in-files failures:** if `ipc.file.search` throws (regex syntax error, IO error), show inline banner in the dialog
-- **REPL:** no IPC, no error handling needed
-- **Git status:** if folder isn't a git repo, return empty array. Panel shows "Not a git repository" message
-- **Print:** if `ipc.file.print` fails (no printer, user cancels), toast.error or silent close
-- **Minimap, Breadcrumbs:** renderer-side, no errors
-
----
-
-## 6. Testing Strategy
-
-- **Unit tests:** `lib/docx-export.ts` (markdown → docx conversion, ASCII handling), `lib/ascii-table.ts` (already tested)
-- **Component tests:** 1-2 smoke tests per new component
-- **Integration test:** `phase9-tools-smoke.test.tsx` covering the 6 command-triggered tools (dispatch opens correct modal/overlay)
-- **Editor integrations:** minimap toggle, breadcrumbs render with symbols, git status panel render
-- **Target: +30-40 new tests**, total ~290
-
----
-
-## 7. Risks & Open Questions
-
-**Risks:**
-- **`docx` lib bundle size (~500KB).** Acceptable for a desktop app but worth noting. Lazy-load if it becomes a concern.
-- **Word export custom template parsing** — the `.dotx` format is a zip with XML inside. The `docx` lib may not fully support reading existing templates. v1 may need a simpler "styles only" extraction.
-- **Find-in-files regex compilation** — invalid regex would throw. Validate on the renderer before calling IPC.
-- **Minimap performance** — for large files, the minimap can slow down scrolling. CodeMirror's built-in minimap has performance options to configure.
-
-**Open questions (deferrable):**
-- **REPL persistence** — should the textarea content survive across modal close/reopen? → Decision: NO for v1. Keep simple.
-- **Git status auto-refresh** — should it auto-refresh every N seconds? → Decision: NO for v1. Manual via `git.refresh` command.
-- **Find-in-files result count limit** — what if there are 10,000 matches? → Decision: limit to 500 results for v1, show "X more matches" message.
-
----
-
-## 8. Out of Scope (deferred to Phase 10 or later)
-
-- Custom undo/redo (still not in scope)
-- Snippet/template library
-- Multi-cursor editing
-- LSP / language server
-- Phase 10 will delete legacy files including the old `src/print-preview.js`, `src/wordTemplateExporter.js`, `src/welcome.js`, `src/zen-mode.js`, etc.
-
----
-
-## 9. Success Criteria
-
-Phase 9 is complete when:
-- All 10 features implemented and accessible via the command store
-- `lib/docx-export.ts` generates valid `.docx` files
-- Find-in-files returns results from a recursive disk walk
-- REPL renders markdown snippet previews
-- Zen mode hides all chrome and Esc exits
-- Print preview opens native print dialog
-- Minimap appears when `useSettingsStore.minimap` is true
-- Breadcrumbs show symbols by default
-- Git status panel shows modified/added/deleted/untracked files
-- ~+30-40 new tests, total ~290
-- `npx vite build` succeeds
-- Branch tagged `phase-9-advanced-tools` and pushed to origin

-# MarkdownConverter — React + shadcn/ui UI Redesign
-
-**Date:** 2026-06-05
-**Status:** Design (awaiting user approval)
-**Branch:** `react-electron`
-**Author:** Brainstormed with user via superpowers:brainstorming
-
-## Summary
-
-Replace the legacy vanilla JS renderer (`src/renderer.js` is 213 KB; `src/styles.css` is 74 KB) with a modern React 19 + Vite + TypeScript + shadcn/ui renderer that achieves visual feature parity while delivering a Polished + Glassy (Raycast/Arc-style) aesthetic. The Electron main process, preload bridge, and IPC contracts stay unchanged. Work proceeds via vertical slices — each PR ships a demoable feature.
-
-## Goals
-
-1. Replace every render-time feature of the legacy renderer with an idiomatic React + shadcn/ui implementation.
-2. Adopt the "Polished + Glassy" visual language (subtle shadows, 8–12 px radii, gradient accents, gentle depth) on top of the existing ConcreteInfo brand tokens and design system.
-3. Use a single component foundation (shadcn/ui) and a single motion library (Motion / Framer Motion) to keep the dependency surface narrow and the design coherent.
-4. Keep the main process, preload, and IPC contracts untouched. The renderer is the only surface being rewritten.
-5. Keep the app runnable at every commit. No "big bang" merge.
-
-## Non-Goals
-
-- Migrating the main process to TypeScript (out of scope for this spec).
-- Adding new features the legacy renderer does not have (plugin system, AI features, etc. — those are future specs).
-- Replacing Pandoc/FFmpeg/ImageMagick orchestration.
-- Changing the packaging pipeline (electron-builder config stays).
-- Replacing the CodeMirror 6 editor — it is the right tool and is already wired up.
-
-## Decisions Locked During Brainstorming
-
-| Decision | Choice | Why |
-|---|---|---|
-| Scope | Full feature parity with legacy renderer | User-selected option. Renderer is one cohesive surface; splitting it across specs would force premature contracts. |
-| Visual style | **B — Polished + Glassy** (Raycast/Arc aesthetic) | "Fancy" comes from elevation, gradient accents, and material depth — not over-designed visuals. |
-| Layout | **2 — IDE-style** (equal editor/preview, draggable divider, collapsible sidebar) | Power-user markdown apps converge on this. Draggable divider + keyboard reset. |
-| Modal patterns | **A (Centered Dialog), B (Right Side-Sheet), D (Toasts)** | No command palette. |
-| Command palette | **No** — full menus, no ⌘K | Power users can use the OS-level launcher. App stays focused on writing. |
-| Animation | **Motion (Framer Motion)** | Best for layout transitions, modal/drawer enter/exit, drag. Sparingly used. |
-| Component library | **shadcn/ui** | Tailwind + Radix primitives, copy-paste ownership, perfect fit for the "glassy" aesthetic and the HSL-CSS-variable foundation that is already in place. |
-| Implementation strategy | **Vertical slices** — one feature end-to-end per PR | App stays runnable. Each PR is reviewable. |
-
-## Defaults (Used Unless Overridden Later)
-
-| Item | Default | Why |
-|---|---|---|
-| State management | Zustand (already in deps) + Immer for nested patches | Already in `package.json`; perfect for editor state. |
-| Theming | shadcn `next-themes`, dark default + light, system-aware | shadcn canonical pattern. Brand colors already in CSS vars. |
-| Icons | `lucide-react` (already in deps) | 1000+ tree-shakable icons. |
-| Forms | `react-hook-form` + `zod` | Standard for shadcn forms. |
-| Drag/drop (sortable lists) | `@dnd-kit/core` | De facto React drag lib (file tree reordering, plugin list reorder). |
-| Pane resize (split layout) | `react-resizable-panels` | Canonical React lib for resizable pane groups; handles drag, arrow keys, snap, persisted sizes. |
-| Testing | Vitest + RTL + Playwright (E2E + visual regression) | Standard for React + Electron. |
-| TypeScript | Strict mode (already wired) | Already in deps and `vite.renderer.config.ts`. |
-
-## Architecture
-
-The Electron app keeps its existing process model. Only the renderer is rewritten.

-
-### Architectural Rules
-
-- **Shell components** (`AppHeader`, `TabBar`, `StatusBar`) subscribe only to `useAppStore`.
-- **Feature components** subscribe to their own feature's store.
-- **Cross-feature access** goes through hooks, not direct store imports (e.g., `useFileTree()` wraps `useFileStore`).
-- **Feature modules are self-contained** — each owns its components, its Zustand slice, and its types. Safe to develop in parallel later.
-- **No direct `window.electronAPI` calls** from feature code. All IPC goes through `lib/ipc.ts` for type safety and error normalization.
-
-## State Management
-
-```
-stores/
-├─ useAppStore        // global UI: theme, sidebar, pane sizes, modals open
-├─ useFileStore       // file system: tree, open files, active tab
-├─ useEditorStore     // editor: per-file content, cursor, selection, dirty
-├─ usePreviewStore    // preview: scroll sync, zoom, theme
-├─ useSettingsStore   // user prefs (persisted to electron-store)
-└─ useCommandStore    // menu actions registry, recent actions
-```
-
-**Why slices instead of one mega-store?** Editor content can be megabytes. Keeping it in its own slice lets React avoid re-rendering the preview when only the editor changes — components subscribe with selectors.
-
-**Persistent state** (auto-saved to electron-store via Zustand `persist` middleware): theme, sidebar visibility, last open files, pane divider positions, settings.
-
-**Ephemeral state** (lost on quit): active modal, hover states, search query, current file content (saved to disk on idle).
-
-## Visual Design System
-
-### Color Tokens
-
-The existing `globals.css` HSL variables stay. Additions for the "glassy" aesthetic:
-
-```css
---shadow-sm: 0 1px 2px rgba(13, 11, 9, 0.06);
---shadow-md: 0 4px 12px rgba(13, 11, 9, 0.08), 0 0 0 1px rgba(13, 11, 9, 0.04);
---shadow-lg: 0 12px 32px rgba(13, 11, 9, 0.12), 0 0 0 1px rgba(13, 11, 9, 0.06);
---shadow-glow-brand: 0 0 24px rgba(229, 70, 31, 0.25);
-
---glass-bg-light: rgba(255, 255, 255, 0.72);
---glass-bg-dark:  rgba(13, 11, 9, 0.72);
---glass-border-light: rgba(255, 255, 255, 0.4);
---glass-border-dark:  rgba(255, 255, 255, 0.08);
-```
-
-### shadcn Components
-
-Install via `npx shadcn@latest add`:
-
-**Primitives** (need all of these): `button`, `dialog`, `sheet`, `popover`, `tooltip`, `select`, `dropdown-menu`, `tabs`, `separator`, `scroll-area`, `toggle`, `switch`, `slider`, `input`, `textarea`, `label`, `form`, `skeleton`, `sonner`, `command`.
-
-**Composite** (custom-built on top of primitives): `file-tree`, `pane-group`, `divider`, `status-bar`, `menu-bar`, `toast`.
-
-### Typography
-
-- Body: Plus Jakarta Sans 15 px / line-height 1.6
-- Code: JetBrains Mono 13.5 px
-- Display: Barlow Condensed 700/800 — used sparingly (page titles, big metrics)
-- Headings: Plus Jakarta Sans 600/700 with tight letter-spacing
-- Labels (`.label`): Plus Jakarta Sans 500, 12 px, uppercase, 0.05 em letter-spacing
-
-### Motion Choreography
-
-| Element | Motion | Duration | Easing |
-|---|---|---|---|
-| Modal (Dialog A) | Scale 0.96→1, opacity 0→1 | 200 ms | `ease-out` |
-| Side sheet (B) | TranslateX 100%→0, opacity 0→1 | 300 ms | `cubic-bezier(0.16, 1, 0.3, 1)` |
-| Toast | TranslateY 100%→0, opacity | 250 ms | spring(stiffness: 300, damping: 30) |
-| Sidebar toggle | Width 264 px↔72 px, content fade | 250 ms | `ease-in-out` |
-| Divider drag | Live width update | 0 ms | none (instant) |
-| Theme switch | CSS variables, opacity overlay | 300 ms | `ease-in-out` |
-| Tab switch | Underline slide | 200 ms | `ease-out` |
-| Hover (buttons) | `bg` + `shadow` shift | 150 ms | `ease-out` |
-| Focus ring | Outline grow | 100 ms | `ease-out` |
-
-**Rules:** Every motion has a purpose. No gratuitous animation. Respects `prefers-reduced-motion` (Motion handles this automatically).
-
-### Empty / Loading / Error States
-
-Every async surface ships all three. Sonner toasts for ephemeral feedback. Skeleton screens for content areas. Empty-state components with icon + message + primary CTA.
-
-## Modal/Overlay Patterns
-
-| Use case | Pattern | Why |
-|---|---|---|
-| Export (PDF/DOCX/HTML) | A — Centered Dialog | Focused decision, ~3–5 fields, "do one thing" |
-| Settings | B — Right Side-Sheet | Long form, tabbed sections, stays open while editing |
-| Find/Replace | Inline toolbar (not modal) | Always-visible utility |
-| About | A — Centered Dialog | Tiny info dump |
-| Confirm destructive (delete, close unsaved) | A — Centered Dialog | Forces attention |
-| File save error | D — Toast | Non-blocking info |
-| Pandoc/FFmpeg progress | D — Toast → sticky on >3 s | Background work feedback |
-| Plugin manager | B — Right Side-Sheet | Lists + per-item actions |
-| ASCII/Table generators | A — Centered Dialog | Tool-style focused input → output |
-| Print preview | A — Centered Dialog | Full-screen-ish modal overlay |
-| Welcome (first launch) | A — Centered Dialog | One-time onboarding |
-| Word export | A — Centered Dialog | Template selection |
-| Zen mode | Full-viewport toggle (no modal) | Replaces the editor entirely |
-| REPL | Bottom-pinned panel (split-pane) | Persistent terminal-like UI |
-| Quick file open | B — Right Side-Sheet | File tree, search, recent |

-
-### Side-Sheet B Anatomy (Settings as example)
-
-Slides in from right, ~50 % width (max 560 px). Backdrop is `rgba(13,11,9,0.2)` with `backdrop-blur(2 px)` (lighter than dialog — the sheet is the focus). Tab navigation in the sheet header (Editor / Theme / Export / Plugins / About).
-
-### Toast D Anatomy (Sonner)
-
-Stacked bottom-right, max 3 visible. Glass background. Color-coded 3 px left border — success `#1a7a56`, error `#ef4444`, info `#0ea5e9`, warning `#eab308`. Icon + title + description. Optional action button. Auto-dismiss 4 s for success, sticky for error.

-PreviewPane renders HTML
-  KaTeX post-processes $...$
-  Mermaid post-processes ```mermaid
-  Highlight.js post-processes ```lang
-  ↓
-useEffect: scroll-sync editor cursor → preview position
-```
-
-**Bidirectional scroll sync:** editor scroll → preview (primary), preview click → editor cursor (secondary). Throttled to 60 fps via `requestAnimationFrame`.
-
-## IPC Contract
-
-The preload bridge stays unchanged. A new `src/renderer/lib/ipc.ts` wraps every channel with TypeScript types and normalizes errors to a discriminated union:
-
-```ts
-type IpcResult<T> =
-  | { ok: true; data: T }
-  | { ok: false; error: { code: string; message: string } };
-
-export const ipc = {
-  file: {
-    open: (): Promise<IpcResult<FileResult>>,
-    read: (path: string): Promise<IpcResult<string>>,
-    write: (path: string, content: string): Promise<IpcResult<void>>,
-    list: (dir: string): Promise<IpcResult<FileEntry[]>>,
-    onChange: (cb: (path: string) => void) => () => void,
-  },
-  export: {
-    pdf: (opts: PdfOptions): Promise<IpcResult<ExportResult>>,
-    docx: (opts: DocxOptions): Promise<IpcResult<ExportResult>>,
-    html: (opts: HtmlOptions): Promise<IpcResult<ExportResult>>,
-    batch: (items: BatchItem[], opts: BatchOptions): Promise<IpcResult<BatchResult>>,
-  },
-  app: {
-    getVersion: (): Promise<IpcResult<string>>,
-    openExternal: (url: string): Promise<IpcResult<void>>,
-    showItemInFolder: (path: string): Promise<IpcResult<void>>,
-  },
-};
-```
-
-## Error Handling
-
-Layered defense — no single failure can crash the app:
-
-1. **IPC errors** → caught in `lib/ipc.ts` wrapper, returned as `IpcResult<T>` discriminated union. Components show toast on error.
-2. **Component errors** → React error boundary per feature area (one for editor, one for preview, one for modals). On error: show inline error UI with "Reload this panel" + "Copy details" actions.
-3. **Async operations** (export, file ops) → loading state on button + toast on completion. Long ops (>2 s) get a sticky toast with cancel.
-4. **Validation errors** (settings, export options) → inline form errors via `react-hook-form` + `zod`. shadcn `Form` component for consistent error display.
-5. **Pandoc/FFmpeg missing** → detected at startup, banner + disable export menu items. Don't surprise-fail at export time.
-
-## Testing Strategy
-
-- **Unit (Vitest):** stores, hooks, lib utilities, formatters, validators
-- **Component (Vitest + RTL):** shadcn wrappers, dialog interactions, sidebar toggle, divider drag, theme toggle
-- **Integration (Vitest + RTL):** editor ↔ preview flow, file open → tab add → content display, settings change persists
-- **E2E (Playwright):** app launches, file opens, markdown renders, export to PDF works
-- **Visual regression (Playwright snapshots):** locked-in screenshots for header, sidebar, dialogs, toasts — catch accidental style drift
-- **Target coverage:** stores/hooks/lib ≥ 90 %, components ≥ 75 %, E2E covers all critical paths
-
-## Accessibility (WCAG 2.1 AA)
-
-Baked in via shadcn + Radix:
-
-- All dialogs focus-trap, Esc to close, return focus to trigger
-- All interactive elements keyboard-reachable
-- Visible focus rings (2 px brand ring)
-- 4.5:1 contrast minimum (already met by brand colors)
-- `aria-label` on icon buttons, `role="alert"` on toasts
-- Respects `prefers-reduced-motion` (Motion handles this automatically)
-
-## Implementation Phases (Vertical Slices)
-
-Each phase is a shippable PR that keeps the app runnable. The legacy `renderer.js` is gradually replaced; until each phase is complete, the old renderer code still runs the missing parts.
-
-| # | Phase | Output | Acceptance |
-|---|---|---|---|
-| 1 | **Foundation** | shadcn installed; `next-themes`, `motion`, `react-hook-form`, `zod`, `@dnd-kit/core`, `react-resizable-panels`, `sonner` installed; design tokens finalized; `lib/utils.ts` (`cn`), `lib/ipc.ts` typed wrappers, `lib/motion.ts` preset transitions, `App.tsx` shell skeleton renders | `npm run build` succeeds; dev server shows the new shell with theme toggle working |
-| 2 | **App shell + layout** | `AppHeader`, `TabBar`, `Toolbar`, `Breadcrumb`, `StatusBar`, `ResizablePaneGroup` with sidebar toggle and draggable divider. Empty editor/preview panes. | Resize divider with mouse and arrow keys; sidebar collapses; pane sizes persist. |
-| 3 | **Editor pane** | CodeMirror 6 wrapped, dark/light themes wired to shadcn theme, syntax highlighting, line numbers, search, autocomplete | Open `.md` file → renders in editor; can edit and save. |
-| 4 | **Preview pane** | marked + DOMPurify + KaTeX + Mermaid + highlight.js. Bidirectional scroll sync with editor. | Open file → preview renders, follows cursor. |
-| 5 | **File tree + tabs** | Sidebar file tree (read directory on demand, lazy-expand children only on click). Tabs for open files. Dirty state indicator. File content is read from disk only when the tab is activated. | Open folder → root populates; click folder → children load; click file → opens in tab; close tab reverts dirty. |
-| 6 | **Native menus + toolbar** | Replace the legacy `CommandPalette` with full menus (File / Edit / View / Insert / Format / Tools / Help) bound to keyboard shortcuts. Toolbar buttons. | All menu items invoke the right action; shortcuts work; toolbar reflects active state. |
-| 7 | **Modals** | Export dialog (PDF/DOCX/HTML/batch), Settings side-sheet (Editor/Theme/Export/Plugins/About tabs), About dialog, Confirm-destructive dialog | All dialogs and sheet render with proper motion; settings persist; export works end-to-end. |
-| 8 | **Toasts** | Sonner wired into all async operations (save, export, errors, tool missing) | All operations give appropriate feedback; no silent failures. |
-| 9 | **Advanced tools** | Zen mode (full-viewport toggle), REPL (bottom-pinned panel), ASCII generator, Table generator, Word export template picker, Print preview | Each tool is feature-complete vs. legacy version. |
-| 10 | **Polish + delete legacy** | Visual regression snapshots locked; remove `renderer.js` and old `styles*.css` references from build; `npm run build:linux` produces a working installer | Final PR ships an installer with no legacy code paths. |
-
-## Risks and Mitigations
-
-| Risk | Mitigation |
-|---|---|
-| shadcn CLI requires Vite (not vanilla Electron renderer) | Vite is already configured for the renderer in `vite.renderer.config.ts`; the CLI works against the same project. |
-| shadcn CLI assumes Tailwind is at project root; we have it in renderer/ only | Point the CLI at `src/renderer/components.json` and set `tailwind.css` to the right path. |
-| Marked + KaTeX + Mermaid + highlight.js together is heavy | Lazy-load Mermaid (only when `mermaid` code block encountered). KaTeX is loaded once, cached. |
-| Editor content state can be megabytes → re-render storms | Editor content lives in its own slice; preview subscribes to a derived/cached HTML string; components use `useShallow` / selector subscriptions. |
-| Bidirectional scroll sync loops | `useEffect` debounce + ignore if cursor/selection is the sync source. |
-| CodeMirror 6 doesn't ship a Tailwind theme by default | Use `@codemirror/theme-one-dark` for dark; build a custom theme that pulls from CSS variables for light. |
-| The legacy `renderer.js` and `styles*.css` are referenced from `index.html` (now `src/renderer/index.html`) | Phase 10 deletes the references; until then, both run side-by-side and the new React app sits in a known root div. |
-| Electron `nodeIntegration` is off; we use contextBridge | Already the case. Document the contract clearly in `lib/ipc.ts`. |
-
-## Open Questions (to confirm before implementation)
-
-None. All major decisions are locked. Defaults will be used unless the user overrides them when reviewing the implementation plan.

-# Phase 10 — Polish + Delete Legacy Design
-
-> Companion to the parent plan: `docs/superpowers/plans/2026-06-05-react-ui-redesign.md` (Phase 10 is sketched at high level; this spec locks architecture, file map, deletion targets, and version strategy.)
-
-**Date:** 2026-06-06
-**Phase:** 10 of 10 (React + shadcn/ui UI redesign) — **FINAL**
-**Tag (on completion):** `v5.0.0` (the first release tag, all prior phases were `phase-N-*` working tags)
-
----
-
-## 1. Goal & Non-Goals
-
-**Goal:** Finalize the React UI redesign. Decompose the legacy 146KB `src/main.js` into a feature-first modular structure under `src/main/`, remove the legacy vanilla-JS renderer and all dead IPC bridges, then ship **v5.0.0** with a CHANGELOG.
-
-**Non-goals (Phase 10):**
-- Adding new features (Phases 1-9 shipped all of them)
-- A full main-process test suite (the existing main process is largely untested; adding tests is Phase 11+)
-- Backwards compat shims for the legacy renderer
-- Renderer-side refactor (already done)
-- Migrating the renderer build pipeline further (vite configs are in place)
-
-**Success criteria:**
-- `src/main.js` is gone; `src/main/index.js` is the new entrypoint
-- `package.json#main` points to `src/main/index.js`
-- All 12 legacy renderer files are deleted
-- All 9 dead IPC channels are removed from `preload.js` and `main.js`
-- `src/index.html` is reduced to ~50 lines (just the Vite bootstrap)
-- `package.json#version` is `5.0.0`
-- `CHANGELOG.md` exists in Keep a Changelog 1.1.0 format
-- `git grep -E "renderer\.js|command-palette|print-preview|welcome\.js|zen-mode|wordTemplate|ascii-generator|table-generator|styles\.css"` returns zero results
-- All 305 tests still pass
-- `npx vite build --config vite.renderer.config.ts` succeeds
-- `npx electron .` launches and main window renders
-- Tag `v5.0.0` pushed to origin

-
-**Module rules:**
-- Each file has one clear responsibility (no god files; CLAUDE.md says >300 lines is the cap)
-- `index.js` is the public face of a folder; deeper files are private
-- `src/main/index.js` (top-level) wires everything together
-- Cross-folder imports go through `index.js`, not directly to internals
-
-### 2.2 Entry point change
-
-**Before:**
-```json
-// package.json
-"main": "src/main.js"
-```
-
-**After:**
-```json
-// package.json
-"main": "src/main/index.js"
-```
-
-The new `src/main/index.js` runs the same `app.whenReady().then(...)` flow that the current `src/main.js` does, but composes the decomposed modules.
-
-### 2.3 What becomes dead code (removed during decomposition)
-
-When the legacy renderer files are deleted, these main-process functions become orphaned and are removed too:
-

-
-### 3.2 Dead IPC channels to remove from `src/preload.js`
-
-- `toggle-command-palette` (line 238)
-- `open-ascii-generator` (line 89)
-- `open-table-generator` (line 92)
-- `print-preview` (line 173)
-- `print-preview-styled` (line 174)
-- `show-table-generator` (line 180)
-- `show-ascii-generator-window` (line 217)
-- `show-ascii-generator` (line 218)
-- `show-table-generator-window` (line 221)
-
-And from the exposed API surface:
-- `openAscii: () => ipcRenderer.send('open-ascii-generator')` (line 445)
-- `openTable: () => ipcRenderer.send('open-table-generator')` (line 446)
-
-**9 channel names + 2 API entries to remove.**
-
-### 3.3 Legacy references in `src/index.html` (16 places) — **the LEGACY file at project root, 1667 lines**
-
-- `<link rel="stylesheet" href="styles.css">` (line ~6)
-- `<link rel="stylesheet" href="styles-welcome.css">` (line ~7)
-- `<div id="print-preview-overlay" class="modal hidden" ...>` block (~10 lines)
-- `<div class="command-palette-overlay hidden" id="command-palette-overlay">` block (~5 lines)
-- `<script src="renderer.js"></script>` (final script tag)
-
-**All of these are removed by deleting the file `src/index.html` entirely.**
-
-The CURRENT live renderer template is **`src/renderer/index.html`** (already correct: minimal, CSP, Plus Jakarta Sans font, `<script type="module" src="./main.tsx">`). This file is **NOT touched** in Phase 10. Vite's `root` is set to `src/renderer/` in `vite.renderer.config.ts`, so `src/renderer/index.html` is the HTML template Vite uses. The `src/index.html` at the project root is an orphan from the pre-Vite era.
-
-**Verification:** after deleting `src/index.html`, the renderer build still works because Vite doesn't look at the project root — it uses `src/renderer/index.html`.
-
-### 3.4 Main process rewiring
-
-- Remove `require('./wordTemplateExporter')` from main entrypoint
-- Remove `webContents.send('print-preview*')` and `webContents.send('toggle-command-palette')` from menu items
-- Remove `ipcMain.on('open-ascii-generator', ...)` and `ipcMain.on('open-table-generator', ...)` handlers
-- Remove `asciiGeneratorWindow` and `tableGeneratorWindow` global state (and any references to `loadFile(...ascii-generator.html)` / `loadFile(...table-generator.html)`)
-
----
-
-## 4. `src/index.html` — DELETE (not rewrite)
-
-The current `src/index.html` is 1667 lines of legacy markup and is **DELETED** (not rewritten). The renderer is already correctly served by `src/renderer/index.html` (the Vite root). Deleting the legacy root-level `src/index.html` is the action — no replacement file is needed.
-
-`src/renderer/index.html` (already correct) is NOT modified:
-
-```html

-## 5. Version Bump + CHANGELOG
-
-### 5.1 `package.json`
-
-```diff
--  "version": "4.4.2",
-+  "version": "5.0.0",
-```
-
-Major version bump because the legacy renderer removal is a breaking change for anyone who had plugins/integrations pointing at `src/renderer.js`.
-
-### 5.2 `CHANGELOG.md` (new file, Keep a Changelog 1.1.0 format)
-
-```markdown
-# Changelog
-
-All notable changes to markdown-converter will be documented in this file.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
-and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
-
-## [5.0.0] - 2026-06-06
-
-### Added
-- **Complete React 19 + Vite + TypeScript renderer** replacing the legacy vanilla-JS UI
-- Native macOS/Windows/Linux menus with command palette and keyboard shortcuts
-- Settings sheet (5 tabs: editor, theme, keybindings, advanced, about)
-- Modal layer with 13 modal kinds (export PDF/DOCX/HTML/Word, batch, settings, about, welcome, confirm, ASCII gen, table gen, find in files)
-- 10 advanced tools: ASCII generator, table generator, Word export, find-in-files, REPL, print preview, zen mode, minimap, breadcrumbs-with-symbols, git status
-- Sonner toast notifications at 4 wire points
-- 3 mount strategies: ModalLayer dialogs, App.tsx overlays, editor/sidebar integrations
-- `ipc.file.writeBuffer` for renderer-side binary output
-- `ipc.file.search` (recursive regex), `ipc.file.gitStatus`, `ipc.print.show`, `ipc.app.showSaveDialog`
-- 305 unit + integration tests (vitest + React Testing Library)
-- Per-package @radix-ui primitives
-- shadcn/ui (new-york style) primitives
-
-### Changed
-- **BREAKING**: Renderer is now React-only.
-- Main process decomposed from 146KB `src/main.js` into feature-first modules under `src/main/`
-- `src/index.html` reduced from 1667 to ~50 lines
-- IPC contract: handlers throw, `safeCall` catches → `{ ok, error }`
-- Settings store: `useSettingsStore` (zustand persist with zod)
-- Modal state: `useAppStore.modal: ModalState` discriminated union
-
-### Removed
-- `src/renderer.js` (legacy vanilla-JS renderer, 5319 lines) — and `src/index.html` (1667 lines of legacy markup, replaced by `src/renderer/index.html` which is already the live Vite template)
-- 7 legacy stylesheets (styles.css, styles-modern.css, styles-concreteinfo.css, styles-sidebar.css, styles-zen.css, styles-welcome.css, fonts.css)
-- 5 legacy scripts (command-palette.js, print-preview.js, welcome.js, zen-mode.js, wordTemplateExporter.js)
-- 2 legacy HTMLs (ascii-generator.html, table-generator.html)
-- 9 dead IPC channels (toggle-command-palette, open-*/show-* ascii/table, print-preview*)
-```
-
----
-
-## 6. Task Decomposition
-
-**10 tasks** (each independently verifiable, one feature per commit, no bundling):
-
-1. **Decompose main.js — `src/main/files/`** (file ops facade, search, git, binary)
-2. **Decompose main.js — `src/main/menu/`** (buildMenu + items, with dead sends removed)
-3. **Decompose main.js — `src/main/window/`** (createMainWindow ONLY — ascii/table windows removed)
-4. **Decompose main.js — `src/main/word-template/`** (WordTemplateExporter split into parser/converter/apply)
-5. **Decompose main.js — `src/main/utils/` + `store.js` + `ipc.js` + `index.js`** (glue + new entrypoint)
-6. **Trim preload.js** — remove 9 dead IPC channels + 2 exposed API entries
-7. **Delete legacy renderer files** (13 files: renderer.js, 7 styles, fonts.css, 4 scripts, 3 htmls)
-8. **Verify src/renderer/index.html is the live template** (no action needed if it's already correct)
-9. **Bump package.json version to 5.0.0 + write CHANGELOG.md**
-10. **Final verification + tag v5.0.0** (build, tests, grep, electron smoke)
-
-Tasks 1-5 are subagent-driven (decomposition is mechanical given a clear target structure). Tasks 6-9 are direct edits. Task 10 is a verification gate.
-
----
-
-## 7. Verification Strategy
-
-**Per task:**
-- After each decomposition step: `npx vitest run` (305 still green)
-- After main.js decomposition: `npx electron .` smoke — app starts, opens a file
-- After deletions: `git grep -E "renderer\.js|command-palette|print-preview|welcome\.js|zen-mode|wordTemplate|ascii-generator|table-generator|styles\.css"` returns ZERO results
-
-**Final (Task 10):**
-- `npx vitest run` — 305 passing
-- `npx vite build --config vite.renderer.config.ts` — succeeds
-- `npx vite build --config vite.preload.config.ts` — succeeds
-- `npx electron .` — app launches, main window renders
-- Manual smoke: open a `.md` file, edit it, export to PDF/DOCX, use the command palette
-- `git tag -a v5.0.0 -m "..."` and `git push origin v5.0.0`
-
----
-
-## 8. Risks & Open Questions
-
-**Risks:**
-- **Decomposition regressions.** Splitting a 146KB main.js into 7+ files has surface area for missed imports / circular deps. Mitigation: tests stay green; electron smoke after each step.
-- **Hidden legacy references.** `git grep` won't catch references inside minified bundles or in node_modules. Mitigation: vite build will fail if there's a dangling import.
-- **`src/main/index.js` entrypoint change.** Anything in the build pipeline (electron-builder, scripts) that hardcodes `src/main.js` needs to be updated. Mitigation: grep all of `package.json`, `scripts/`, `vite.*.config.ts` for `main.js`.
-
-**Open questions (resolved during brainstorming):**
-- ~~Main process scope~~ → Full rewrite
-- ~~Folder shape~~ → Feature-first
-- ~~IPC migration~~ → Delete dead channels
-- ~~Version strategy~~ → v5.0.0 with Keep a Changelog format
-- ~~Order of work~~ → Decompose first, delete last
-
----
-
-## 9. Out of Scope (deferred to Phase 11+)
-
-- Main process test suite
-- Renderer-side further refactor
-- New features
-- Migration to tauri (separate plan in `docs/plans/2026-03-15-react-tauri-pwa.md`)
-
----
-
-## 10. Success Criteria
-
-Phase 10 is complete when:
-- All 10 tasks are committed, one per commit, no bundling
-- `src/main/index.js` is the new entrypoint
-- All 12 legacy files are deleted
-- All 9 dead IPC channels are removed
-- `package.json#version` is `5.0.0`, `package.json#main` is `src/main/index.js`
-- `CHANGELOG.md` exists with a complete v5.0.0 entry
-- 305 tests still pass
-- `npx vite build` succeeds for both renderer and preload configs
-- `npx electron .` launches and the app works end-to-end
-- `git grep` for legacy references returns zero results
-- Tag `v5.0.0` is created and pushed to origin
-- Phase 10 is the LAST phase of the React UI redesign
