/**
 * Styled Discount Cards - CSS v4.0.1
 *
 * REDESIGNED: Modern mobile-first cards with visual hierarchy,
 * link underline fix, image round corners, refined typography
 *
 * Design system: Green primary, amber verdict, tier accents
 *
 * v4.0.1: Migrated onto Deal Design System — canonical --ds-* tokens with literal
 *         fallbacks (deep teal #0F766E on white), Plus Jakarta Sans body font.
 *         Tokens + font ONLY: every class name / selector / HTML / data-* attribute
 *         UNCHANGED. Amber verdict, tier accents and pale-green code box left intact.
 *         Dark-mode :root override block deliberately untouched.
