Frontend Performance & Core Web Vitals (Stub)
Core Web Vitals focus on user-centric performance metrics (LCP, CLS, INP). Optimizing them improves perceived speed and engagement.
To Be Expanded
- Definitions & threshold table
- Image optimization (responsive, lazy-loading)
- Bundle splitting & code splitting
- Caching strategies (HTTP, service worker)
