Animated asset pipeline

Turns a one-line idea ("a cheerful corgi") into a rigged voxel creature with 13 animation clips, exported as glTF. Four stages, each with a QA gate. Run them in order; never skip a gate — a bad early artifact wastes every later stage.

Exactly ONE gate is a manual user pick — present the material, then stop and wait:

1. concept selection (stage 1): the user picks one of four generated concept images. Every other gate is automated; ask the user only when one fails twice in a row.
