/* Tripwire: the Breaker Box (see docs/DESIGN.md). The console is one object: a dark enclosure with a breaker per product.
   Checkouts run in on the top bus from the shop, through each product's breaker, and out on the bottom bus to PayPal.
   A wrong price trips that breaker; the checkouts that hit it stop at the gap. One signal colour (orange) = tripped.
   The rules are objects: only the merchant's lever resets a breaker, the AI can only light its lamp, and more than five
   checkouts in a minute heat a fuse that trips it. One family, Archivo. Every hue, size and corner below is a token. */
