/* ==========================================================================
   DESIGN TOKENS
   Palette: paper-green background, deep emerald primary, lime accent used
   sparingly on the "swap" motif, coral for the "was $X" struck price.
   Type: Space Grotesk (display), Inter (body), IBM Plex Mono (price/data).
   Signature element: the Price Swap tag — a struck original price that
   resolves to a lime "Free" pill. It repeats on cards, hero and categories
   so the whole site reads as one continuous "what you save" ledger.
