   Motion layer
   - Hover / press micro-interactions (pure CSS, spring easing)
   - Ambient loops
   - Initial states for elements that js/motion.js animates in.
     These only apply under html.has-motion, which is set when
     reduced motion is off and removed if Motion fails to load.
   Hover lifts use the independent `translate` / `scale` properties
   so they compose with Motion's inline `transform`.
