/* Mumbai Local Panic — HUD chrome.
   ART DIRECTION: matches sprites/backgrounds/day.png — deep slate rail-corridor panels
   (#1f242b), Indian-Railways mustard-gold signboard headers (#f9b93f sampled from the map's
   signage), warm cream ink, map-blue and bus-red accents. Chunky pixel borders (hard box-
   shadows, no glossy gradients, no rounded-modern-web). The canvas is the star.
   LAYOUT: full-height map pane in the MIDDLE; TWO independently scrollable signboard columns
   (~clamp(320px,22vw,400px) each): LEFT = dispatcher side (DispatcherPanel pinned header,
   AI log + PA ticker, notifications, rosters), RIGHT = player side (TopBar pinned header,
   meters incl. energy, card bar, pinned NextTurn footer). */
