/* =====================================================================
   ARCADE: a cabinet's game-select screen. PICO-8 palette on navy, Silkscreen
   pixel type for labels and numbers, IBM Plex Mono for reading, square
   corners, notched "pixel" frames and scanlines over everything.
   Yellow is the one accent.
   Spec: docs/themes/arcade.md

   THE FRAME RULE (read docs/themes/arcade.md before changing anything here):
   every framed element, game cards included, has a LIGHT GREY (#c2c3c7)
   notched frame. The frame is never the game's colour: the colour lives only
   in the icon block. The toast is the one yellow frame at rest; a hovered game
   card, button or theme button lights its frame yellow (a danger button red),
   and pressing turns it orange.
   Every --pb below is set with plain specificity, so what you read is what
   renders: never put an id inside the shared :is() frame selector.
