Changes for David's Injury Atlas, 2 October 2026: selected left radius, ulna, proximal carpals and one dorsal intercarpal ligament; unpacked source positions/normals/indices without smoothing; cropped proximal shafts; split radius triangles at an authored extra-articular metaphyseal plane with interpolated imported normals; triangulated two closed fracture surfaces; authored illustrative distal-fragment rotation/translation and rigid associated carpal/cartilage motion. Fracture parameters are educational choices, not a scan or clinically validated case. Reference source assets are intact; runtime affected geometry is this adaptation. Ligament deformation and tendons are absent.

Independent original application code and teaching prose are distinct from the adapted anatomy assets. Three.js licence is MIT; its full notice is retained separately.
