🔧 Constraints & Trade-offs

Technical Constraints

1. Browser Compatibility

• Constraint: Modern CSS features (flexbox, grid, custom properties)
• Trade-off: Limited support for older browsers (IE11 and below)
• Solution: Progressive enhancement with fallbacks

2. Print Layout Complexity

• Constraint: A4 formatting must survive print/export
• Trade-off: Complex CSS with print media queries
• Solution: Dedicated print styles that hide UI elements

3. State Management

• Constraint: Complex document state with multiple pages
• Trade-off: Custom hook vs. external state management
• Solution: Custom useDocumentState hook for simplicity

4. Tiptap Extension Limitations

• Constraint: Some desired extensions don't exist (page breaks, line height)
• Trade-off: Custom implementation vs. missing features
• Solution: Custom visual page break indicators

Performance Constraints

1. Large Document Handling

• Constraint: Memory usage with many pages
• Trade-off: Virtual scrolling vs. full rendering
• Solution: Current approach renders all pages (acceptable for typical use)

2. Real-time Updates

• Constraint: Editor updates on every keystroke
• Trade-off: Debouncing vs. immediate updates
• Solution: Direct updates for responsive feel
