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: -
