/* ==========================================================================
   WIZKET — rush.css · "Rush hour" game (Software page, #play)
   A toy back office: tickets drop into the inbox, you sort them into three bins.
   Round 2 adds a conveyor belt and the system sorts everything itself.
   js/rush.js sets data-state on .rs (idle · play · switch · auto · done) and places
   every ticket (absolute, inside the board). Ticket kinds wear their own colours;
   orange stays for the switch, the stamp and the CTA. Prefix: rs-
