/* ==========================================================================
   Battlesnake Arena design system — "Direction E: Two-Toggle Themes"
   Minimal editorial: warm paper, hairline rules, mono data, pink accent.

   Two theme axes, resolved onto html[data-app-theme="light|dark"]:
     - site theme    (system | light | dark)  — every page
     - game theater  (match | dark | light)   — pages marked data-theater-page
   Resolution happens in the inline head script (no-FOUC) + /static/theme.js.
