/* --------------------------------------------------------------------------
   SQDCIP board — dark theme
   Built for a screen on a wall. The background is black so the room's lighting
   does not wash it out, the letters are heavy shapes lifted off the surface by
   a shadow, and status is told only by the two colours the method already uses.
   Nothing else on the page is allowed to be colourful, so one red day is the
   loudest thing on the screen from across the shop floor.
