/* ============================================================
   richolson-missile-command — hand-written scoped overrides
   ------------------------------------------------------------
   Atomic prepends the compiled Tailwind v4 bundle ABOVE this block.
   This file holds only scoped, hand-authored rules:
     1. the palette tokens (flip under a .dark ancestor — class-based
        dark mode owned by the site shell). The <canvas> game reads
        these at runtime so it re-themes with the site;
     2. the canvas presentation + a subtle CRT scanline overlay;
     3. small keyframes for the HUD glow / banner.
   Scoped under .custom-section-richolson-missile-command so nothing leaks.
