Dashboard tiles tumble onto the belt from the left and pile up while it scrolls right at a steady linear pace. The amber "0 SCANNED" counter blinks on each downbeat of bar 4, just before the drop.
The camera cranes down onto the arch roof; the lead curtain flaps swing as the belt restarts. On the drop the teal spill blooms outward, the mark and "Acme Pulse" light, and the status LEDs tick on one per 16th note.
Packages glide left to right; as each crosses the arch a clip-path wipe flips it to X-ray. #2231 lights coral, the pusher arm snaps it down onto the tray on a downbeat (back.out), the monitor punches in, and the human hits "Roll back" while the belt keeps rolling above.
The camera tilts up off the belt, which keeps scrolling below as a metronome. The tagline slams in word by word on quarter notes; teal ticks pop onto each passing package on the last bar and the coral button lands on the final downbeat.
