/* DealMade storefront (index-xd.html) — production styling.
   Derived from the Figma "Shop" frame (node 3:9422, 375px wide):
   header 122px, hero 244px, section headers 18px/500 Noto Sans KR, product
   cards (brand / name / blue discount% + price), circular brand rail, and a
   fixed 5-tab bottom bar. Mobile-first at 375; widens into a desktop shell.

   Data is bound live from /api (deals + products); the luxury items in the
   Figma mock are the designer's placeholder content and are never hardcoded. */
