/* Realmbreak grading bench (src/screens/grading.mjs). The bench steps through classes on .gr:
   is-in → is-scan → m-0 … m-3 (centering, corners, edges, surface) → is-calc → is-cased → is-slam → is-ready.
   Every finished state is a plain style; animations only describe how it arrives, so with motion off
   (body.no-motion / prefers-reduced-motion) the bench still shows the complete slab. --gc is the grade tier colour,
   --rc the rarity colour, --sc one measurement's colour. Uses --cond and --frame from styles/arena.css. */
