/* trivvy — the answer board. theme.css owns colour; this file owns the
   board's material: panels, letter tabs, the bulb rail, segment digits,
   and how each surface (screen, controller, host) lays them out.

   Grammar, so a new screen can be built without guessing:
   .tv-panel       a cream card with a letter tab; face-up shows text,
                   face-down (.is-down) is a dark blank, lit (.is-lit)
                   is the amber reveal, dim (.is-dim) is a loser.
   .tv-rail        the incandescent bulb border; --lit bulbs of --bulbs
                   stay on, the rest are dark: it IS the timer.
   .tv-seg         seven-segment digits over ghost cells.
   .tv-marquee     the question, condensed caps on a lit strip.
   Display face is League Gothic; body is the theme's sans. */
