Evidence & model coverage

249,949 web triangles; 9 supplied geometry groups before runtime flattening. Generic mesh chunks are not physical components.

Changes: Texture cap 512px (JPEG 85 for opaque images, PNG for transparency); duplicate/unused data removed; welded vertices; error-bounded simplification (0.001 relative tolerance; borders may change); Draco encoding; supplied mesh-bearing nodes retained.

Chelydra serpentina preserved/taxidermy specimen scan. At one million triangles, budget for retopology/LOD and texture work. Do not imply a live capture, rig or medically validated internal anatomy.
