Accuracy notes

Real-paper follow-along and paper weight have not been tested. Diagrams illustrate the sequence, not paper thickness, contact, collisions or exact layer visibility. One uncut square with original material coordinates and rigid hinge motions. Shaping distances are authored teaching landmarks, not measurements supplied by the reference. Zero-thickness teaching diagrams do not certify thickness, contact or physical foldability. Real-paper folding has not been tested.
