/* ============================================================================
   Vega Bell - auth.css
   Styles for public/js/screens/auth.js and public/js/screens/tuning.js.
   Conforms to docs/DESIGN_SYSTEM.md. Depends on tokens.css + animations.css.

   TWO RULES KEEP THIS FILE OUT OF EVERYONE ELSE'S WAY:

   1. SCOPED. index.html loads app.css, screens.css and game.css around this
      file, and game.css owns its own `.tile` / `.tiles` / `.speaker`. So every
      rule below is scoped under `.auth` or `.tune` (the two root wrappers
      these screens render). That both stops this file leaking into other
      screens and wins inside these two regardless of link order.

   2. LAYERED FALLBACKS. `.panel`, `.btn` and `.icon` belong to the app shell
      (app.js and ui.js emit them). They are defined here inside
      `@layer vb-fallback` purely so these screens are never unstyled -
      unlayered rules always beat layered ones, so app.css wins automatically.
