   /assets/motion.js (IntersectionObserver at 12% visibility).

   P0 contract (stranger audit, 2026-06-11): CONTENT IS NEVER
   HIDDEN WHILE WAITING. There is no standing opacity:0 state —
   every element renders fully visible in every browser, with or
   without JS, observer or no observer. The entrance exists only
   as a finite animation that motion.js triggers when the
   observer ACTUALLY FIRES for an element that was below the
   viewport at scan time. Headless browsers, readers, and
   JS-degraded clients simply see a complete, still page.

   The animation drives the `translate` property (not transform)
   so it composes with tilt transforms on .card.tilt-l/.tilt-r
   and never fights the hover-lift transitions. Sibling stagger
   comes from --reveal-index, capped at 5 (max 6-item stagger).
