Black ink brush calligraphy in a flowing cursive script fills an off-white field, with small red seal stamps along the left edge. Three rounded charcoal frames, each crossed by a thin gold band and holding a single bold character, disguise the finder squares. The dark modules are made of thick, swelling brush strokes and ink drops scattered between them. Strong black on white contrast and the clear gaps between strokes keep the pattern legible as a code, and the ink edges stay crisp and varied in weight.
