Evidence & model coverage

60,000 web triangles; 1 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; Draco encoding; supplied mesh-bearing nodes retained.
