/* ASHFALL Motion System foundation — plan 14 §A.
   NEW file (kept out of app.css to avoid contention with the parallel session).
   Provides easing tokens + opt-in helper classes/keyframes. Does NOT restyle
   existing elements; the big per-surface retrofit happens later, coordinated.
   Use via window.Anim (anim.js) or by adding classes. Honors reduced-motion. */
