/* ---------------------------------------------------------------------------
   tokens.css — the room.

   House rule for this whole site: the chrome is achromatic. Every saturated
   colour you see belongs to a game and arrives per-cabinet as --g-light,
   --g-glow, --g-ink and --g-deep. Nothing in here may add a competing hue.
   The single exception is --attract, which is reserved for focus and active
   state, because those need to stay constant while everything else changes.
