Seamless Harlequin Pattern Black & White

A seamless repeating harlequin pattern composed of 12 rows and 12 columns of very small alternating black and white diamonds within each repeat tile. Every diamond is identical in size, evenly spaced, and slightly elongated vertically to create a classic harlequin lattice. Perfect bird's-eye view (90-degree top-down orthographic projection), flat 2D vector illustration, crisp sharp geometric edges, high-contrast monochrome black and white, no perspective, no shadows, no gradients, no texture, no lighting effects, no bevels, perfectly aligned, seamless tile repeat, ultra-high-resolution textile pattern suitable for all-over printing.
