 * Global header: top bar, main row (branding/search/account/cart),

 * Authored desktop-first: unprefixed rules describe the desktop layout;
 * max-width queries at 1024px (tablet) and 767px (phone) restructure the
 * layout rather than just shrinking it — header row reflows, search moves
 * to its own row, and the category bar becomes a collapsible drawer.
