Evidence & model coverage
242,597 web triangles; 3 supplied geometry groups before runtime flattening. Generic mesh chunks are not physical components. Object_4 is the visually verified complete cover. Only the cover lifts; the vessel body spans two source groups. This is an inspection aid, not a validated mechanism.
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.

}Historical medical practice should be interpreted as history, not modern treatment guidance.
242,597 triangles and two materials warrant optimization for mobile delivery.
