| Largest Contentful Paint (LCP) | < 2.5s | Time for main content to render |
| First Input Delay (FID) | < 100ms | Time until page becomes interactive |
| Cumulative Layout Shift (CLS) | < 0.1 | Visual stability during loading |
| Time to First Byte (TTFB) | < 600ms | Server response time |
| First Contentful Paint (FCP) | < 1.8s | Time until first content appears |
