/* Zawaya room motion contract. Tokens only; rs-language.css owns the shapes.
   Frame budget at 60 Hz: 16.7 ms total, with at most 2 ms main-thread
   scripting and 3 ms compositor work for a focus move. No more than three
   layers move at once (rs-motion.js books every arrival into one of three
   lanes); the streak gets one layer for under 200 ms. Animate transform and
   opacity ONLY.
   No layout or paint property may change mid-transition. Never animate blur:
   any softness must be rasterized once at rest, then moved as a cached layer.
   These are budgets to measure on target hardware, not measured timings. */
