const MARKITECT_INSERT_MODE = true;
const MARKITECT_EDITOR_CONFIG = {
mode: 'insert',
restrictedHeadingLevels: [1, 2, 3],
// ... standard editor config
};
```
**Section Enhancement**:
- `Section.detectHeadingLevel()` - Identify heading levels 1-6
- `Section.isProtectedHeading()` - Check if heading is protected in current mode
- `Section.getHeadingText()` - Extract heading text for display
- `Section.getHeadingContent()` - Extract content after heading for editing
**Validation Logic**:
- Pre-acceptance validation ensures protected headings remain unchanged
- Error handling for attempted heading modifications
- Content reconstruction maintains heading + content structure
### Behavioral Differences from Edit Mode
| Feature | Edit Mode | Insert Mode |
|---------|-----------|-------------|
| Heading Levels 1-3 | ✏️ Fully Editable | 🔒 Read-Only Display |
| Heading Levels 4-6 | ✏️ Fully Editable | ✏️ Fully Editable |
| Content Editing | ✏️ Full Section | ✏️ Content Only (for protected) |
| Section Splitting | ✅ All Headings | ✅ All Headings |
| New Heading Creation | ✅ Unlimited | ✅ With Level-Based Protection |
| Theme Support | ✅ All Themes | ✅ All Themes |
### Future Enhancements
- **Configurable Protection Levels**: Allow customization of which heading levels are protected
- **Conditional Protection**: Enable/disable protection based on section content or metadata
- **Protection Indicators**: Visual badges showing protection status in section list
- **Bulk Mode Switching**: Convert between edit and insert modes for existing documents
---
## Design Principles
### 1. **Theme Consistency**
All components must adapt to the selected UI theme:
- **Standard**: Light grey palette with blue accents
- **Greyscale**: Monochromatic grey scale
- **Electric**: Dark blue with cyan/yellow accents and glow effects
- **Psychedelic**: Vibrant gradient backgrounds with white text
### 2. **Non-Blocking Interactions**
- **Toast notifications**: Auto-dismiss, don't require user action
- **Floating action panel**: Always accessible, doesn't block content
- **Inline editors**: Contextual, don't interfere with other sections
### 3. **Graceful Degradation**
- **Content always visible**: Even if JavaScript fails
- **Progressive enhancement**: Core functionality works without advanced features
- **Fallback implementations**: Basic browser dialogs until custom implementations ready
### 4. **Responsive Design**
- **Mobile-first**: Components adapt to smaller screens
- **Touch-friendly**: Appropriate touch targets and gestures
- **Scalable**: Works across different zoom levels and resolutions
### 5. **Accessibility**
- **Keyboard navigation**: All interactive elements accessible via keyboard
- **Screen reader support**: Proper ARIA labels and semantic markup
- **High contrast**: Sufficient color contrast ratios in all themes
- **Focus management**: Clear focus indicators and logical tab order
---
## Development Conventions
### CSS Class Naming
**Pattern**: `{scope}-{component}-{element}-{modifier}`
**Scopes**:
- `ui` - User interface elements
- `md` - Mode (light/dark)
- `dc` - Document content
- `br` - Branding
**Examples**:
- `ui-edit-floater-panel`
- `ui-edit-button-accept`
- `ui-edit-textarea-main`
- `ui-edit-section-frame`
### JavaScript Event Naming
**Pattern**: `{action}-{target}`
**Examples**:
- `edit-started`
- `changes-accepted`
- `section-split`
- `content-updated`
### Component State Management
- **Centralized**: Section state managed by `SectionManager`
- **Event-driven**: Components communicate via events
- **Immutable updates**: State changes create new state objects
- **Consistent**: Same patterns across all components
