/* Contraption Lab: the Inventor's Workshop look Doug picked (6 Oct, "wood style"): a pegboard wall, a wooden
   bench for the board, brass and copper parts, cream cards with brown ink, Fraunces for titles and Fredoka for
   reading. Its own look; games.css only gives the shared rules (no selecting text, the Back button, pop-ups). */
