/motion-audit — Motion Audit

Audit every animation and transition:

1. List all transition properties and durations
2. List all @keyframes animations
3. Flag animations on layout properties (width, height, top, left) — should use transform
4. Flag durations over 400ms without justification
5. Check for prefers-reduced-motion fallback
6. Count simultaneous animations (>3 is too many)
7. Verify custom easing curves are used (not just 'ease')
