-### v1.9.1 ASCII Art & Code Block Preservation
-
-#### 🎨 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>
