/* ==========================================================================
   ARCADE — Build with it (Design Completion Campaign, 2026-09-29).
   More screens of the room's machine: the same cyan border and magenta
   ring, pixel headings in yellow, Space Mono for reading, scan lines over
   the whole board, and a HUD of real counts pinned across the top. Faces
   are the room's own ("PressStart2PX", "SpaceMonoX", declared in
   x-arcade.css). Every class is gac- or scoped to .gm--arcade. Motion is
   steps() only, and stops under reduced motion.
