/* Wordfeud Butler — styles
   Design direction: a calm, warm "board game" feel (cream + forest green, echoing icon.svg)
   rather than the old app's flat blue. Tiles are the centerpiece: rendered as physical
   wood/cream Scrabble-style pieces with a corner point value, in both the rack and the
   "remaining tiles" bag view. Mobile-first single column, letterboxed on wide viewports.
   Theme-aware via prefers-color-scheme (light + dark), no framework, no build step.

   General-purpose tokens (surface/text/border/accent/status colors, shadows) now live in
   shared/web/styles/tokens.css - shared project-wide since the single-PWA work
   (plans/project-wide-pwa.md, decision 4), this being the palette it was built from. What is left
   below is only what is genuinely specific to this app: tile rendering (a physical-piece look,
   not a brand color) and the avatar palette (nothing else uses it). */
