DDK adaptations: OBJ-to-GLB conversion, cropping/normalization, knee surface refinement and cut-plane closures, icy-blue/green materials, lighting and matching rendered stills.

Illustrative anatomy, not diagnostic imagery. The knee model contains femur, tibia, patella and fibula, not cartilage or ligaments. Nerve model shows left median/ulnar/radial nerves with forearm-bone context; vein model shows right saphenous veins with tibia context, focused on the lower leg. Models are not patient-specific.
