/* Claude Monet, auction demo: the saleroom during the sale.
   Baize-green walls, one painting on the stand, a split-flap board beside it that flips to each
   lot, and a round paddle to enquire. One accent, the board's amber: digits, the current lot,
   the main button, the paddle ring, focus. Pictures are sharp-cornered; things you press are round
   (pills and the paddle); board cards have a small radius, like the real thing. */
