/* Guest board – runs on bar TVs and must stay readable from across the room.
   Four designs share one frame (header, stage, footer). Sizes inside the stage derive from
   --u (row/tile height in px) and --w (column/tile width in px), measured by board.js, so every
   design uses the largest type that fits, for any number of drinks.
