/* Dzstorex storefront styles.
 *
 * Mobile-first: the base rules target a phone, and the only media query widens
 * to a two-column layout on a large screen. Algerian shoppers are overwhelmingly
 * on a phone, usually on mobile data, so the page ships no framework, no web
 * fonts and no build step - it is hand-written HTML, CSS and one small JS file.
 *
 * Design intent: product-focused. Name, photo, price, availability, order. The
 * availability check is the loudest control on the page because it is the thing
 * that makes the price trustworthy.
