  "description": "Mastercard.com hero reading — the 'left circle' of the dual-circle mark. Cool warm-near-white #F3F0EE canvas (the classic fintech card-face beige), canonical Mastercard red #EB001B as primary, Mastercard yellow #F79E1B secondary as the dual-identity tell quoting the right circle without dominating. Geometric Poppins heading carries the bolder display register vs Stripe's restrained Inter wordmark. Distinguished from coca-cola-classic-red by canvas warmth (Mastercard cool fintech beige vs Coca-Cola warm shelf cream) and brand profile (Mastercard pill-leaning radii + semibold vs Coca-Cola Spencerian script context).",

    "Don't dilute Mastercard red below #EB001B — the canonical hex is what distinguishes this from Coca-Cola red and Pepsi red across the catalog.",
    "Don't promote yellow to primary on light — yellow on white fails WCAG (~1.6:1); the yellow-side reading lives in mastercard-yellow on dark.",
    "Don't drop the deep cyan color-premium override — energy-secondary yellow is in the gold/amber family per Rule 6 (and Rule 8 already accepts the red-as-energy / color-error overlap)."
