The reef.
Three maintenance drones have serviced the same sunken ocean liner for sixty years. Today one of them finds a door that isn't on the chart.

Sixty seconds, written against an eight-second ceiling.
The Reef is a sixty-second animated short built entirely from generated footage. Seedance 2.0 caps a generation at eight seconds, so the film is eight shots of 7.5 seconds rather than a continuous piece — and the cut does the work a camera move would do in live action.
Every character, environment and prop was built first as a named reference element that the shot prompts call by tag. That is what holds three characters consistent across eight separate generations. None of them has a mouth, so all sixteen lines are voiceover and nothing can desync.
The colour arc is the spine. Shots one to five hold a cold, desaturated green-blue with almost no warmth anywhere. Shot six is the only saturated frame in the film. Five shots of restraint buy one shot of colour.

EVERY PROMPT, PUBLISHED
All eleven element prompts and all eight shot prompts are published in full — including the physics, lighting and colour-grade blocks, and the risks table covering what goes wrong and how it was fixed.
They live on the full write-up rather than being repeated here, so there is one canonical copy to link, cite and correct.
