Motion

Duration tokens, Apple-style easing, and the reduced-motion contract.

duration-fast	200ms	hover color and transform	bg:motion:duration-fast
duration-normal	300ms	card hover, FAQ answer collapse	bg:motion:duration-normal
duration-slow	600ms	scroll-reveal transitions	bg:motion:duration-slow
duration-colors	150ms	quick color flips	bg:motion:duration-colors

Easing curves

card-lift-md	translateY(-4px)	bg:motion:card-lift-md

Reduced motion

Hard rule. Every animation must include a @media (prefers-reduced-motion: reduce) override that disables it or replaces it with a static state. The base reset in base.css already neutralises all transitions for reduced-motion users; per-component animations must additionally remove transforms on hover.

@media (prefers-reduced-motion: reduce) {
  *, *::before, *::after {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
    scroll-behavior: auto !important;
  }
}
