/* EasyPay Demo Showcase — partner-onboarding-conversion page
 *
 * Design source: easypay-dashboard/design/DESIGN-SYSTEM.md
 * Local spec:    DESIGN.md (next to this file)
 *
 * Visual DNA matches mini-app dashboard so the partner feels continuity:
 *  - Full-screen teal gradient background
 *  - White cards floating on top
 *  - DM Serif Display only for product price (one focal point per card)
 *  - DM Sans for everything else
 *  - One uniform teal→green hero gradient per product (no per-product palette)
