/* =========================================================================
   Wording: Letter Hunt — web design system.

   Same palette as the mobile app: near-white surfaces, one coral accent, heavy
   rounding. Values are duplicated here rather than shared because the two
   clients have no common styling layer; if the palette changes, both Theme.kt
   and this file need updating.

   Motion here is meant to carry information, not decorate: a tile flips because
   a letter opened, the ring tightens because time is running out, the podium
   rises because someone won. Everything is CSS — no animation library — and all
   of it collapses under prefers-reduced-motion at the end of this file.
