Changes: decompressed geometry, baked transforms, normalized scale, muscle-group mapping and training-coverage materials. The adapted model and its conversion script remain available under CC BY-SA 4.0. No Symmetric Strength artwork is used.

Website adaptation: identical app geometry merged by muscle group into little-endian Float32 vertex/normal buffers and Uint32 index buffers, gzip compressed. No geometric simplification. Browser lighting and group highlights added for the interactive demonstration. The adapted mesh and export-anatomy.py are licensed under CC BY-SA 4.0.
