## Performance Improvements

### Next.js 16 Features
- Enable Partial Prerendering (PPR) via cacheComponents
- Add Turbopack for 4-5x faster development builds
- Implement loading states and error boundaries
- Configure static asset caching (1 year max-age)

### Bundle Size Reduction
- Replace Framer Motion with CSS-only animations (~50KB reduction)
- Dynamic import for SearchModal component (lazy loaded)
- Optimize scroll reveals using IntersectionObserver
- Remove loading attribute from OptimizedVideo (not supported on video elements)

### Image & Video Optimization
- Add responsive sizes attributes to all Image components
- Implement lazy loading for below-fold images
- Add priority loading for hero images
- Convert large GIFs to MP4/WebM formats (80-95% file size reduction)
- Create OptimizedVideo component for efficient video playback

### Search Optimization
- Configure Pagefind to index only essential content
- Add data-pagefind-body wrapper for main content
- Add data-pagefind-meta for tags metadata
- Add data-pagefind-ignore for navigation and related posts
- Result: Cleaner search results, smaller index size

### SEO & Social Media
- Add dynamic OG image generation using @vercel/og
- Enhance metadata with OpenGraph and Twitter Cards
- Generate 1200x630 social images for all posts

### Documentation
- Update README with comprehensive performance optimizations section
- Document Pagefind configuration
- Add GIF to video conversion details

## Technical Details

Video file size reduction:
- AddNewThings3.gif (2.4MB) → WebM (116KB) = 95% reduction
- Things3.gif (1.5MB) → WebM (170KB) = 89% reduction
- Total: 3.9MB → 286KB = 93% reduction

Build output: 49 pages indexed, 5370 words searchable
