/* Tic-Tac-Lab — styles (started from Science Tug of War's). Same game chrome as the other review games (deep navy, gold for the main action,
   raised things on a solid darker bottom edge). Readability floor for a Chromebook at arm's length or a projector:
   body 16px+, HUD 20px+, answers 18px+, the prompt 22-26px, tap targets 48px+. The match fits a 1366x768 window
   (about 1366x650 inside the browser) with no scrolling: the scene (whole-number pixel scale) on top with the board's
   click targets over it, the question / move panel at the bottom, the HUD over the scene. */
