Full-bleed hero backdrop modeled on a rotor cipher machine's stepping mechanism: three letter-wheel windows where the right wheel ticks steadily, kicks the middle wheel once per revolution, and the middle wheel occasionally double-steps, moving twice in one beat and dragging the left wheel with it, the real Enigma-family stepping anomaly compressed to a 9-position ring so it recurs roughly every minute instead of every eleven.
