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.
