## Major CodePress CMS Enhancement

### 🚀 New Features
- **League CommonMark Integration**: Replaced basic Markdown parser with full CommonMark 2.7 support
- **Bootstrap Sass Architecture**: Modern SCSS build system with Bootstrap 5.3.8
- **Enhanced Navigation**: Uses filenames instead of H1 titles for consistency
- **Improved Styling**: Transparent navigation backgrounds, no rounded corners

### 🎨 UI/UX Improvements
- Navigation items now use formatted filenames (e.g., "kennis-boven-aantallen" → "Kennis Boven Aantallen")
- Transparent navigation backgrounds with subtle hover effects
- Removed rounded corners from first-level navigation
- 50% opacity navigation background using Bootstrap variables

### 🔧 Technical Improvements
- **Class Organization**: Extracted CodePressCMS and SimpleTemplate to separate files
- **Full PHPDoc Documentation**: Complete documentation for all methods
- **Modern Build Process**: npm scripts for SCSS compilation
- **Enhanced Markdown Support**: Tables, strikethrough, task lists, autolinks
- **Security**: Proper HTML sanitization with CommonMark

### 📦 Dependencies
- Added `league/commonmark` for professional Markdown parsing
- Added `bootstrap` for SCSS-based styling
- Updated `sass` build process

### 🐛 Bug Fixes
- Fixed content directory path configuration
- Resolved navigation title inconsistencies
- Improved Markdown bold/italic formatting
- Fixed homepage 404 issues

### 🔄 Migration Notes
- Content directory moved from `content/` to `public/content/`
- Navigation now displays filenames instead of content H1 titles
- CSS now compiled from SCSS source files

The CMS now provides a professional, modern experience with robust Markdown support and clean, maintainable code architecture.
