Evidence & model coverage
298,104 web triangles; 14 supplied geometry groups before runtime flattening. Generic mesh chunks are not physical components. Initial camera is inside the captured room. Scan gaps and exterior shell artifacts remain. Official museum upload: The Hallwyl Museum (Hallwylska museet).
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.

}One million triangles; plan an optimized variant.
It is a room/interior model, not a complete exterior building. Give the viewer a useful initial camera and prevent confusing navigation through walls.
