Why it works
The complete question and graph appear at 0.0 s, allowing the viewer to predict an outcome before the path begins. A single 1050-frame locked shot retains each new segment, while highlight p95 rises across the film and the dark field stays near 0.03 mean luma, making the growing density the payoff.
