/* games/index.html and games/<game>.html, on the Signal foundation (the
   study's #/games and #/games/chess). signal-read.css carries the page top,
   sections, bento cards, questions and the closing call; this sheet is the
   game pages' own parts: the painted tiles, the game hero, the numbered
   first match, the usage callout, the next-game row and the board-led
