/* ============================================================
   Sports.Cars — Concept #3 listing page
   Reskins listing.html onto the Concept #3 design language.
   Loaded after concept3.css (shares its tokens, reset, nav,
   footer, .c3-frame corner marks, and .c3-cars/.c3-car grid).

   Deliberately keeps every class/id main.js and marketcheck.js
   hook into (#galleryMain, .gallery__*, .listing-title,
   .listing-price, .spec-table, .seller__name, .btn--primary) so
   the gallery carousel and the live "?id=" MarketCheck hydration
   keep working untouched — only the visuals change here.
