/* 스토어 (G001, look G004: planning/store/design_preview/). Loaded after site.css on /store/ pages only; the colours are site.css
   tokens, no web fonts, no images, and the corner radii (8-12px, pills) follow the approved preview rather than the 0-4px of the rest
   of the site. Nothing here is fixed or sticky: Coupang's operating policy bans floating banners (the preview's bottom buy bar is
   dropped), and the build fails when this file has such a rule. The one script (store.js, main page only) filters the cards.
