/* Offers hub (offers.html) + homepage offers teaser (index.html#offers-teaser).
   Built on the site's existing design tokens from assets/css/main.css
   (--bg, --card, --brand, --brand-2, --accent, --radius, --shadow) so the
   hub reads as CertShield rather than a bolted-on reskin. New tier accent
   colors are additive, not a palette replacement. */
