/* ── Motion ─────────────────────────────────────────────────────────────────
   Everything that hides or moves content is gated behind `html.motion`, which
   js/motion.js adds only when IntersectionObserver exists and the visitor has
   not asked for reduced motion. Without it the pages render as plain static
   layout. js/motion.js adds `.is-inview` as each element scrolls into view.

   Entrances use `animation … backwards` rather than transitions: the element
   holds its `from` state through the delay, then hands back to its normal
   styles, so hover effects on the same element keep working afterwards. */
