tiling(G, datum, r) — a minimal generative surface

1 G — symmetry order the only irreducible input

2 datum choose exactly one

No datum — G alone fixes the tiling.

c — offset gauge, except where it makes grid lines concurrent

ρ — spacing alternate families; concurrency needs exact ratios

k — skew unequal offsets; 0 = exact G-fold about the origin

3 r — radius view, not object

frame view, not object
