/* ==========================================================================================
   app.css — design system + shell screens (owner: shell).
   Platform look (§12.1, mockups Main / NickTaken / Invited / Invite): navy surfaces, blue primary, orange accent,
   Unbounded 800 for display type and Golos Text for everything else (self-hosted, assets/fonts/fonts.css).
   Dark-first; light theme via <html data-theme="light">. Board/game styles live in board.css/game.css.

   Token names other stylesheets rely on are kept (--bg, --surface, --surface-2, --accent, --text, --muted, …);
   Gold is retired (§12.1): the old --gold-grad alias and .chip-gold/.badge-gold classes are gone — use --accent-grad,
   .chip-accent and .badge-accent.
