 *  - Deep teal → emerald gradient background (06222A → 0B3B45 → 0F5C57)
 *  - Type pair: Fraunces (display, prices, italic accents) + Inter Tight (UI/body)
 *  - Numerics: JetBrains Mono, tabular
 *  - White cards on dark, 22px radius, hairline rule above CTA
 *  - One CTA-colour per surface (mint deep on light card)
