Why it works
The opening names a familiar app and a trillion-message scale by 0:03, while the 1.1-second graphic switch prevents a static start. Fourteen shots and 15 internal graphic changes make each database choice and bottleneck visible; the red 125 ms to green 15 ms result at 0:54–0:59 coincides with the strongest replay peak.
