/* ============================================================
   Bomb — the board
   ------------------------------------------------------------
   The setup screen is assets/classroom-setup.css; this is only
   what happens after Start. Sized for a display at the front of
   a room like the other games, and coloured from the shared
   team palette through --team, which classroom-setup.css sets
   for each team's is-* class.

   Up to six teams, so the teams are a strip of cards across the
   top rather than one each side. The bomb is on the left and the
   question on the right; both take the colour of whoever is
   holding it, so the room can see whose problem it is without
   reading anything.
