8-second 1920x1080 video. Vertical split: left half labeled "BEFORE" shows a cluttered mock UI (grey, 12 overlapping windows drawn in CSS), right half "AFTER" shows one clean card. Both halves settle within the first second. A vertical divider line sweeps left to right at 4s, wiping the clutter into the clean state across the full frame. End on "One tool." centered. No audio. **Spectacle beat:** The divider's wipe is the moment — a bright scan-line travels the split with a bloom as it crosses, and the AFTER half resolves behind it.
