hash-design

Library, CLI, Skill and MCP server of hash-design: roll true-random hashes; each hash is a design direction, its bytes mapped by fixed, reproducible rules onto palette, type, grid, density, anchor, motif, surface, motion, voice and twist (no style library) — so AI-built pages stop collapsing into the same template (Inter, purple gradients, centered hero with two buttons, three identical cards…).
