   Points Board — the board
   ------------------------------------------------------------
   The setup screen is assets/classroom-setup.css; this is only
   what happens after Start. Coloured from the shared team
   palette through --team, like Bomb.

   The grid is the whole screen, because it is the thing the
   class reads the game from: which squares are left, who took
   which. A question opens over it and closes back onto it.
