/* engine.css: the look of every escape room. Used with engine.js, after
   /shared/kredits-tokens.css.

   game colours below are set on body, not :root, so the Kredits tokens of
   the same names stay as they are. Room pages colour their diagrams with
   these names: --text, --muted, --line, --bg, --panel, --panel-2, --accent
   (selection, graph lines), --amber (clues and labels), --green, --red, --heat. */
