Rotate the canvas 72 degrees and the field is invariant; slide it any distance and it is not — alignment over repetition.
Every long edge is φ times its short partner, so spacing, type scale, and column rhythm inherit the same mathematical bond.
Thirteenth-century Girih craftsmen tiled the same field five centuries before the 1974 mathematics — heritage now formal.
