/* ============================================================
   grammar-verbwheel.css — Verb Wheel (radial spin).

   Loaded alongside grammar-match.css (shared gm- frame chrome + tokens).
   Ported from the legacy grammar.css vwheel rules; the --vw-* palette is
   remapped onto the gm- tokens so the wheel matches the frame. The
   geometry pixel vars (--tile etc.) are written by the engine's autoFit().
