/* ── Motion ──────────────────────────────────────────────────────────────────
   ONE easing curve for everything. Entrances are opacity plus a 4-14px
   translate. No scale-ups, no bounce on hover, no parallax.

   AMBIENT ANIMATION CONTRACT — every self-running system on a page must:
     1. stop when it is off screen (IntersectionObserver),
     2. stop when the tab is hidden (document.hidden),
     3. pause on hover and hold a user's explicit click,
     4. freeze in a FULLY DRAWN resting state under prefers-reduced-motion.
   A loop that would be caught mid-crawl in a screenshot or a PDF is a bug. */
