/* ==========================================================================
   BASE — tokens, reset, typography, buttons, forms, shell.
   Black + gold/orange "arcade collector" look. Pure CSS, no JavaScript.
   Performance rules used across the stylesheets:
     • animate only transform / opacity (compositor-friendly), never layout or big gradients
     • no blend modes, no backdrop-filter, no box-shadow animation
     • off-screen grid cells use content-visibility:auto
     • body.fx-lite (Settings) and prefers-reduced-motion switch every animation off
