Tibetan mani stones are flat river slate carved with the sunk-relief mantra *Om mani padme hum* in Uchen script, then stacked into low walls along pilgrimage routes. The background is chiseled away around each letter so the glyphs stand at the surface, their grooves holding faint weathered traces of symbolic pigment — white, red, and gold — against cool blue-gray stone.

This design system distills that devotional craft into a digital language: a dark slate ground, incised typographic relief, monochrome restraint, and pigment used only as the faintest accent — never bright, never warm.
