- per-frame hips-centred rendering + root-motion export (the BKB .geo approach modernised): traveling clips stay pivot-stable, movement data goes to root_motion_frames in data.json - engine: frame-indexed root motion, pushbox widened for real sprites - clip set: ginga idle, walks, jump, block, punching/boxing/martelo normals, chapa-giratoria QCF special, hit react, knockdown - verified in-game: demo jab connects, damage applied, mirroring correct Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

"""Pack rendered frames into a character folder (CHARACTER_SPEC.md).
|
|
|
|
Takes a renders directory laid out as renders/<char>/<move>/*.png and
|
|
assembles characters/<char>/ with a data.json template per move (timing
|
|
fields to be tuned by hand, hurtboxes to be filled by autohitbox.py).

Usage:
