  "description": "Muji's kraft-cream storefront reading — the Kenya-Hara *ma* aesthetic translated into Void Energy chrome. Cream canvas evoking unbleached-paper packaging, deepened Muji-red #a82e2e as the single saturated signal (the canonical roundel red lifted just enough to clear 7.6:1 on white surface), warm kraft-brown secondary echoing cardboard, deep ink text. The brand profile asserts identity through breathing room and absence: zero radii, regular weights only, wide positive tracking, slow tea-ceremony pacing, +15% density. Distinguished from aesop-apothecary-light by typographic register (Helvetica-class neutral sans vs Cormorant Garamond apothecary serif) and from chanel-couture-light by transform (Muji never uppercases — the wordmark is lowercase running text, the antithesis of Chanel Didone caps).",

  "antiPatterns": [
    "Don't lift bg-canvas to pure white — the kraft cream #f7f5f0 evokes unbleached-paper packaging that distinguishes Muji from generic light atmospheres; pure white belongs to MoMA / gallery-institution territory.",
    "Don't substitute Muji-red with a brighter saturation — the deepened #a82e2e is the white-surface-engineered version of the canonical roundel red; brightening past the canonical hex loses the engraved-tag identity.",
    "Don't introduce uppercase transforms or heavy display weights — Muji's design philosophy (Kenya Hara) rejects display ornament; the brand voice is lowercase wordmark + regular-weight running text. Uppercase would re-introduce the chrome Muji refuses.",
    "Don't drop the deep cyan color-premium override — energy-secondary's warm kraft brown sits in the amber-brown family per Rule 6 and would collide with the default amber-brown premium."
