  "description": "Nike's 1972-era origin reading — the earliest Swoosh on athletic-orange with ember-red accents, recast as a flat-dark poster. Charcoal canvas, pure black sunk-floor for the locker-room shadow, athletic-orange #fa5400 driving energy with the deeper Tinker-red #d30005 as the support hue. Distinguished from nike-volt-dark by family (heritage orange/red vs electric Volt) and from nike-retro by physics (flat product-page vs CRT phosphor). Geometric headings + uppercase buttons carry the Nike chrome — the brand's voice runs hot, not cool.",

  "antiPatterns": [
    "Don't dilute the orange — substituting #ff7733 or higher loses the 1972 athletic heat; the canonical hex is #fa5400.",
    "Don't drop the cyan color-premium override — energy-primary lives in the gold/orange family per Rule 6 and would collide with the default amber-brown premium.",
    "Don't lift bg-canvas above #1a1a1a — the locker-room dark is load-bearing for the heritage poster reading."
