31st procedural texture: classic argyle pattern done by working in a 45-rotated coord system (u, v) = (x+y, x-y) so lozenges become axis-aligned squares for the checkerboard step. Diagonal stitch lines fall out of u%cell and v%cell crossing zero. Three-color: A/B for the alternating diamond fill, third color for the diagonal stitch overlay. Defaults to 64-pixel cells with 2-pixel stitches. Useful for sweater fabric, seat cushions, heraldic banner overlays.
