Performance & Testing

Ship less, measure more. Test across devices, orientations, and network conditions.

Quick Wins

• Minify and inline critical CSS; defer the rest.
• Use system fonts or a small, well‑subset webfont.
• Lazy‑load images/video and avoid large JS bundles.
• Audit with Lighthouse and check CLS, LCP, INP.

Debug Responsiveness

1. Use your browser’s responsive mode (Ctrl/Cmd+Shift+M).
2. Test zoom at 200–400% for low‑vision scenarios.
3. Toggle light/dark and reduced‑motion preferences.
4. Throttle network/CPU to simulate low‑end devices.
