/* style.css — public catalog, mobile-first.
 *
 * A marketplace-shaped storefront: a full-height slide-in category menu, a
 * persistent search field, a category chip rail, a 2-up product grid, and a
 * product page with a swipeable image carousel + breadcrumb. The shell copies
 * the patterns shoppers already know from big resale apps; the skin keeps the
 * store's own identity — a serif carries each product name, a monospace carries
 * every price, a single hairline "shelf rule" sits the price under the name.
 * No web fonts.
