16.8× faster video generation: distilling Wan 2.2 from 40 steps to 4

A public, no-training LoRA cuts Wan 2.2 A14B from 809 s to 48 s per clip on one A100 (16.8×), held across 13 scenes. The full path to that number: the evaluation-count budget that set the target, the distilled output that came back washed-out, the color grade that half-fixed it, and the checkpoint swap that fixed it for free.
