chore(release): bump version to 4.4.5

Pre-process markdown before Word/DOCX export to remove raw HTML artifacts

(<style> blocks, HTML comments, and <div align=...> tags) that were

visible in the generated document. Applies to single and batch DOCX exports

via both Pandoc and WordTemplateExporter paths.

+# CLAUDE.md — MarkdownConverter (master)
+
+> General code-quality, JavaScript, git, security, and testing standards are in the **global CLAUDE.md**. This file holds project- and branch-specific notes.
+
+## Project Overview
+
+Electron desktop app for Markdown editing and universal file conversion powered by Pandoc. Cross-platform (Win/macOS/Linux). Features: multi-tab editor with live preview, 25+ themes, PDF viewer/editor (merge/split/compress/rotate/watermark/password), export to 20+ formats (PDF/DOCX/ODT/EPUB/HTML/LaTeX/RTF/PPTX), batch conversion, syntax highlighting, diagram support (Mermaid), Git integration, and a plugin system.
+
+- **Version:** 4.4.5
+- **License:** MIT
+- **App ID:** `com.concreteinfo.markdownconverter`
+
+## Branch Specifics
+
+This is the **primary/release branch** — a vanilla JavaScript Electron app with no bundler or framework in the renderer. The renderer is a single large `renderer.js` (5,300+ lines) loaded directly via `src/index.html`. All UI is hand-rolled DOM manipulation.
+
+## Architecture
+
+### Main Process (`src/main.js` — 4,260 lines)
+Monolithic main process file. Contains all IPC handlers, Pandoc invocation, file operations, menu definitions (600+ lines), and window lifecycle. Key modules extracted:
+- `src/main/PDFOperations.js` — PDF manipulation via `pdf-lib` (merge, split, compress, rotate, delete, reorder, watermark, encrypt, decrypt, permissions)
+- `src/main/GitOperations.js` — Git status/stage/commit/log via `simple-git`
+
+### Renderer (`src/renderer.js` — 5,361 lines)
+Vanilla JS, no framework. Directly manipulates DOM. Loads CodeMirror 6 via `src/editor/codemirror-setup.js`. Uses `marked` + `highlight.js` + `DOMPurify` + `mermaid` for rendering. Lazy-loads sidebar panels, REPL, command palette, zen mode.
+
+### Preload (`src/preload.js` — 448 lines)
+Exists as IPC bridge, but **`contextIsolation: false` and `nodeIntegration: true`** — the renderer has full Node access. Preload is effectively a thin passthrough.
+
+### Security Model
+- `contextIsolation: false` + `nodeIntegration: true` (legacy; the react-electron branch fixes this)
+- Pandoc invoked via `execFile` (not `exec`) to prevent shell injection
+- Path traversal protection: `validatePath()`, `resolveWritablePath()`, blocks sensitive system dirs
+- Permission handler only allows `clipboard-read`/`clipboard-write`
+- Rate limiter on conversions (2-second minimum interval)
+- File size limit: 50MB
+- Error message sanitization strips absolute paths
+
+### Plugin System (`src/plugins/`)
+Manifest-based discovery (`manifest.json`). Built-in `writing-studio` plugin with sprint/goal/snapshot management. Plugin API exposed via `src/plugins/plugin-api.js`.
+
+### Settings
+Custom JSON file store at `<userData>/settings.json` (NOT `electron-store` despite the dependency). Recent files at `<userData>/recent-files.json`.
+
+## System Dependencies
+
+| Dependency | Required | Notes |
+|---|---|---|
+| **Node.js** | >= 20 | Electron 41 bundles Node 20.x |
+| **Pandoc** | Yes (for exports) | Downloaded to `bin/<platform>/pandoc` via `scripts/download-tools.js` (v3.9.0.2). Falls back to system PATH. Must be present for DOCX/ODT/EPUB/LaTeX/PPTX export. |
+| **FFmpeg** | Bundled | `ffmpeg-static` npm package; `asarUnpacked` for packaged builds |
+| **MiKTeX / TeX Live** | Optional | For LaTeX PDF export; MiKTeX PATH injected on Windows automatically |
+| **ImageMagick** | Optional | Linux image conversion; listed as deb dependency |
+| **LibreOffice** | Optional | Enhanced document conversion; listed as deb dependency |
+
+## Development Commands
+
+```bash
+npm start                  # Launch Electron app (dev mode)
+npm test                   # Jest test suite
+npm test:watch             # Jest in watch mode
+npm test:coverage          # Jest with coverage report
+npm run lint               # ESLint check (src + tests)
+npm run lint:fix           # ESLint auto-fix
+npm run format             # Prettier write
+npm run format:check       # Prettier check only
+npm run download-tools     # Download Pandoc binaries to bin/
+npm run generate-icons     # Generate app icons via sharp
+```
+
+## Build & Package
+
+**Tool:** `electron-builder` (v26.0.12), config inline in `package.json` (no separate config file).
+
+| Target | Platforms |
+|---|---|
+| `npm run build` | electron-builder (default platform) |
+| `npm run build:win` | Windows: NSIS installer + portable + zip (x64) |
+| `npm run build:mac` | macOS: default dmg |
+| `npm run build:linux` | Linux: deb + AppImage + snap |
+| `npm run dist` | Build without publish |
+| `npm run dist:all` | Build for all platforms |
+
+**Bundled with builds:** Pandoc binary per platform. FFmpeg via `ffmpeg-static` (asarUnpacked). NSIS installer uses custom script at `scripts/nsis-installer.nsh`.
+
+**Output:** `dist/` directory.
+
+**CI:** GitHub Actions workflows in `.github/workflows/` (ci.yml, release.yml).
+
+## Project Conventions / Gotchas
+
+- **No bundler/transpilation.** The app uses vanilla CommonJS JavaScript. `src/main.js` is loaded directly by Electron. No webpack, no Vite, no TypeScript, no Babel.
+- **Monolithic files.** `main.js` (4,260 lines) and `renderer.js` (5,361 lines) contain most logic. Not ideal but is the current state of this branch.
+- **CodeMirror 6** for the editor, configured in `src/editor/codemirror-setup.js`.
+- **PDF rendering** uses `pdfjs-dist`; **PDF manipulation** uses `pdf-lib` in the main process.
+- **Renderer security is weak** — full Node access in renderer. Do NOT introduce new privileged renderer code without understanding this.
+- **Pandoc is external.** Must be installed separately or downloaded via `npm run download-tools`. HTML and built-in PDF export work without Pandoc; other formats require it.
+- **PDF export fallback chain:** xelatex -> pdflatex -> lualatex -> Electron built-in `printToPDF()`.
+- **ESLint flat config** (`eslint.config.js`) with ECMAScript 2022. Prettier with 2-space indent, single quotes, semicolons, 100-char width.
+- **Tests:** Jest with jsdom environment, 15% coverage threshold. 24 test files in `tests/`.
+- **File associations:** `.md`, `.markdown`, `.pdf` registered at install.
+- **Single instance lock** enforced via `app.requestSingleInstanceLock()`.
+- **Adapters layer** (`src/adapters/`) abstracts file system operations for potential future non-Electron targets.

-# 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.

-
-**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.
