Why this retention structure works
- 0–1.0s: extreme face macro = pattern interrupt; nothing to read, no logo, no title card.
- New beat every 2s — every lyric line gets its own camera move, background and SFX.
- Kid payoffs every 3–5s: pop, splash, twinkle, giggle — the toddler attention pattern.
- Loop seam is invisible: shot 16's star burst resolves into shot 1's giant eyes at the same zoom, same flash value.
- No sign-off ("thanks for watching" kills replay); the last line feeds straight back into line 1.
Kid-safe motion rubric kept: no whip pans, no shaky cam, no scary angles — the "camera" always moves toward the character. Fast cuts come from scene changes, not from camera violence.
