"""Apply hand-tuned frame data + manifests to the real fighters.

Run after pack_character.py. Timing values are modern fighting-game pacing
(60Hz ticks — see STUDY.md §2), NOT the source clip lengths: `total` compresses
or stretches the sprite sequence to gameplay speed. Values are per-move design
data — tweak freely and re-run.
