/* ── workout.log shared motion primitives (WS0) ──────────────────────────
   One motion recipe used everywhere per design-handoff SPEC.md "Motion standard":
   expand/collapse (chevron rotate 180deg over .2s + wlOpen fade/rise), press states
   (cards scale(.975), buttons/chips scale(.88-.94), ~100ms), drag-lift (lifted item
   scale(1.02-1.03) + deep shadow, displaced rows slide .18s ease), and the wlFill
   bar-fill keyframes used on Session Complete's accomplishment bars.

   Not yet adopted by any screen (WS0 is file-split + primitives only) - screens wire
   these classes in when their own work package lands (WS1-WS11). Built entirely on
   tokens.css variables (see css/workout.css :root); zero hard-coded colors here. */

   specificity and wins on load order, which silently killed the lift shadow. Change
   the shadow HERE; the overrides reference it. (Batch B serial sweep, 2026-08-13.) */
