/* RABLA — css/coop.css (Phase 4, C3; PHASE4_SPEC §5)
   The co-op UI: PARTY tab of the online panel (roster, roles, friends → INVITE), the incoming invite
   card, the lobby card on the level intro, the engineer ability bar + rider note while PLAYING, the
   LAUNCH WITH / LAND WITH prompts, the FOLLOW pill in SPACE and the shared results row. Colours are the
   :root tokens of style.css; everything is in stage pixels (1280×720). Every element is created / shown by
   js/ui/coop.js only while WM.party is active, so single-player never sees any of it. */
