/* Marketplace — an Amazon/Flipkart-style ecommerce theme: dark functional
   header, filled CTA buttons, dense product-grid-ready cards, sans-serif
   throughout. Same selector names as the original design handoff so
   templates don't need to change — only the tokens and component styling
   underneath do. System font stack: no external font request, no CDN
   dependency, matches how real marketplaces actually ship type. Primary
   accent is green rather than Amazon's orange, to keep the palette clear
   of trademark association. */
