Why it works
The opening names the subject at 0:00 and turns it into a bridge image by about 0:02, then uses the same white-bar, teal-joint, green-arrow grammar to move from basic geometry to real structures. At 5:36 it shifts into a solvable example; the 5:39.5–5:50.1 span is the most replayed portion of the measured six-minute excerpt. The measured one-shot/zero-cut result undercounts visible animation states, so it should not be treated as the edit rhythm.
