Release v1.9.1: ASCII Art & Code Block Preservation

Fixed export of ASCII art, charts, tables, and flowcharts to match preview exactly:

🎨 ASCII Art Preservation:
- Code blocks now export exactly as shown in preview
- Each line rendered separately to preserve exact spacing and alignment
- Monospace font (Consolas) used consistently across all export formats
- Line breaks, spacing, and box-drawing characters preserved perfectly

📝 Word Template Exporter Improvements:
- createCodeBlockXml: Renders each line as separate paragraph with exact spacing
- Added <w:keepLines/> and <w:wordWrap w:val="0"/> for no-wrap behavior
- Enhanced isAsciiArt detection with more Unicode box-drawing characters
- Added support for rounded corners (╭╮╯╰), heavy box chars, more arrows

📄 PDF Export Enhancements:
- Added -V monofont="Consolas" for proper code block rendering
- Added --highlight-style=tango for syntax highlighting
- Applied to main export, fallback engines, and CLI conversion

🖨️ HTML/Electron PDF Improvements:
- Enhanced CSS: white-space: pre, word-wrap: normal
- font-family: Consolas, Monaco, 'Courier New', monospace
- Print media queries preserve code block formatting
- overflow: visible prevents content truncation

🔧 Technical Changes:
- src/wordTemplateExporter.js: Enhanced code block and ASCII art rendering
- src/main.js: Added monofont settings to all PDF export paths
- Updated version to 1.9.1

-### v1.7.9 Enhanced Word Export with Template Support (Latest)
+### v1.9.1 ASCII Art & Code Block Preservation (Latest)
+
+#### 🎨 Preserved ASCII Art in Exports
+**ASCII Art, Charts, Tables & Flowcharts Now Export Exactly as Previewed** (`src/wordTemplateExporter.js`, `src/main.js`)
+
+**Problem Solved:**
+- Previously, ASCII art, flowcharts, and code blocks were being corrupted during export to Word and PDF
+- Line breaks, spacing, and monospace alignment were lost
+- Box-drawing characters and diagrams became unreadable
+
+**Solution Implemented:**
+1. **Enhanced Word Template Exporter** (`src/wordTemplateExporter.js:259-289`)
+   - Code blocks now render each line as a separate paragraph with exact spacing
+   - `white-space: pre` and `word-wrap: normal` prevent text wrapping
+   - Monospace font (Consolas) with consistent 18pt size
+   - Light gray background (#F5F5F5) for visual distinction
+   - `<w:keepLines/>` and `<w:wordWrap w:val="0"/>` preserve exact formatting
+
+2. **Improved ASCII Art Detection** (`src/wordTemplateExporter.js:410-456`)
+   - Extended Unicode box-drawing character support (╭╮╯╰ rounded corners, heavy box characters)
+   - Additional arrow characters (↔↕⇒⇐⇓⇑)
+   - More ASCII patterns detected (+---+---+, <---->, etc.)
+   - Better markdown table vs ASCII art differentiation
+
+3. **Enhanced PDF Export** (`src/main.js:1266-1268`, `src/main.js:1345-1347`, `src/main.js:2410-2412`)
+   - Added `-V monofont="Consolas"` for monospace code blocks
+   - Added `--highlight-style=tango` for syntax highlighting
+   - Applied to main export, fallback export, and CLI conversion
+
+4. **Electron PDF Fallback** (`src/main.js:1613-1637`)
+   - Enhanced CSS for `<pre>` and `<code>` elements
+   - `white-space: pre` prevents wrapping
+   - `font-family: Consolas, Monaco, 'Courier New', monospace`
+   - Print media query preserves formatting when printing
+
+5. **HTML Export** (`src/main.js:1525-1548`)
+   - Same CSS improvements as Electron PDF
+   - Code blocks maintain exact preview appearance
+
+**Key CSS Properties for ASCII Preservation:**
+```css
+pre {
+    white-space: pre;
+    word-wrap: normal;
+    font-family: Consolas, Monaco, 'Courier New', monospace;
+    font-size: 12px;
+    line-height: 1.4;
+}
+pre code {
+    white-space: pre;
+    word-wrap: normal;
+    display: block;
+}
+```
+
+**Word XML Properties for ASCII Preservation:**
+```xml
+<w:pPr>
+    <w:spacing w:line="240" w:lineRule="exact"/>
+    <w:keepLines/>
+    <w:wordWrap w:val="0"/>
+</w:pPr>
+<w:rPr>
+    <w:rFonts w:ascii="Consolas" w:hAnsi="Consolas" w:cs="Consolas"/>
+    <w:noProof/>
+</w:rPr>
+```

+
+### v1.9.0 Custom Headers & Footers
+
+#### 📄 Comprehensive Header & Footer System
+**Custom Headers & Footers for Standard Exports** (`src/main.js:701-853`, `src/index.html:929-1042`, `src/renderer.js:2560-2747`, `src/styles.css:3162-3432`)
+- **New Menu Option**: File → "Header & Footer Settings..." to configure headers/footers
+- **Three-Column Layout**: Left, Center, and Right positioning for both headers and footers
+- **Dynamic Field Support**: $PAGE$, $TOTAL$, $DATE$, $TIME$, $TITLE$, $AUTHOR$, $FILENAME$
+- **Logo/Image Embedding**: Upload logos to display in headers and footers
+- **Enable/Disable Toggle**: Quick on/off switch for all headers/footers
+- **Persistent Settings**: Configurations saved across sessions
+
+**Format Support:**
+- **PDF Export** (Standard): LaTeX-based headers/footers using fancyhdr package with automatic page numbering
+- **DOCX Export** (Standard): Word XML manipulation with field support for PAGE and NUMPAGES
+- **ODT Export**: OpenDocument format support (similar to DOCX implementation)
+- **PowerPoint (PPTX)**: Footer text with dynamic fields on slides
+- **Batch Converter**: Full header/footer support for all batch conversions
+
+**Dynamic Fields Processing:**
+- `$PAGE$` → Current page number (LaTeX: \thepage, Word: PAGE field)
+- `$TOTAL$` → Total pages (LaTeX: \pageref{LastPage}, Word: NUMPAGES field)
+- `$DATE$` → Current date (processed at export time)
+- `$TIME$` → Current time (processed at export time)
+- `$TITLE$` → Document title (from metadata or filename)
+- `$AUTHOR$` → Document author (from metadata)
+- `$FILENAME$` → File name without extension
+
+**Technical Implementation:**
+```javascript
+// processDynamicFields function in main.js
+function processDynamicFields(text, metadata = {}) {
+  const now = new Date();
+  result = text.replace(/\$DATE\$/g, now.toLocaleDateString());
+  result = result.replace(/\$TIME\$/g, now.toLocaleTimeString());
+  result = result.replace(/\$TITLE\$/g, metadata.title || 'Untitled');
+  // ... other replacements
+  return result;
+}
+
+// LaTeX header generation for PDF exports
+const latexHeader = `
+\\usepackage{fancyhdr}
+\\pagestyle{fancy}
+\\fancyhf{}
+\\lhead{${headerLeft}}
+\\chead{${headerCenter}}
+\\rhead{${headerRight}}
+\\lfoot{${footerLeft}}
+\\cfoot{${footerCenter}} // with \\thepage for page numbers
+\\rfoot{${footerRight}}
+`;
+
+// Word XML generation for DOCX exports
+const footerXml = `<?xml version="1.0"?>
+<w:ftr xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
+  <w:p><w:r><w:t>${footerLeft}</w:t></w:r></w:p>
+  <w:p>
+    <w:fldSimple w:instr="PAGE"/> // Page number field
+    <w:r><w:t> of </w:t></w:r>
+    <w:fldSimple w:instr="NUMPAGES"/> // Total pages field
+  </w:p>
+  <w:p><w:r><w:t>${footerRight}</w:t></w:r></w:p>
+</w:ftr>`;
+```
+
+**Dialog Features:**
+- **Field Insertion Buttons**: Quick-insert dynamic fields via popup dialog
+- **Logo Upload**: Browse and select images for headers/footers
+- **Logo Preview**: Show selected logo filename
+- **Clear Buttons**: Remove uploaded logos
+- **Enable Toggle**: Disable headers/footers without losing settings
+- **Responsive Layout**: Grid-based three-column design
+- **Dark Theme Support**: Complete styling for all 22 themes
+
+**Integration Points:**
+- `buildPandocCommand()` - Adds LaTeX headers for PDF exports
+- `exportWithPandoc()` - Post-processes DOCX with header/footer XML
+- `performBatchConversion()` - Batch support for all formats
+- `addHeaderFooterToDocx()` - DOCX XML manipulation using PizZip
+
+**Dependencies:**
+- **PizZip** (v3.2.0) - ZIP file manipulation for DOCX/ODT
+- **fancyhdr** (LaTeX package) - Advanced headers/footers for PDF
+- **lastpage** (LaTeX package) - Total page count support
+
+**Key Improvements in v1.9.0:**
+1. ✅ Professional headers/footers for all standard export formats
+2. ✅ Dynamic field support with automatic value replacement
+3. ✅ Logo/image embedding in document headers/footers
+4. ✅ Batch converter integration with full header/footer support
+5. ✅ Persistent settings across application sessions
+6. ✅ User-friendly dialog with field insertion helper
+7. ✅ Complete dark theme support
+
+**Note**: Enhanced exports (DOCX Enhanced, PDF Enhanced) use Word templates which already have their own headers/footers defined in the template itself, so this feature specifically targets standard (non-templated) exports.
