/* ============================================================================
   ARCADE — the shared design system.

   One stylesheet, dropped into every game. Everything here is namespaced with
   an `ac-` prefix (class names and custom properties alike) so it can never
   collide with a game's own CSS. Games keep their own palette and layout; this
   file supplies the shared *language*: one spacing scale, one radius scale,
   one elevation recipe, one set of controls, and the account/leaderboard
   chrome that makes the three games read as one platform.

   A game opts into its theme with `<html data-arcade-game="pegfall">`.
