Why it works
The first frame combines stress-test proof, a pointer, a claim and a guide, so the premise is visible before the first cut at frame 85. Shot 3 holds for 246 frames while its internal diagram states track the spoken mechanism; shots 4–8 then test usefulness and show a limit before the question and destination.
