Subset: right clavicle, scapula, humerus, radius, ulna; three deltoid parts;
coracobrachialis, brachialis; two biceps heads; three triceps heads.

Changes: OBJ to JSON conversion, generated smooth normals, illustrative colors.
The source's relative positions and mesh topology are retained. No textures or
muscle fibers are supplied by these assets. This is a reduced-resolution,
incomplete regional subset, not a clinically validated atlas or surgical model.
