/* Admin backoffice layout, PLUS shared form/card/table/badge/alert
   components reused by public pages that have admin-style forms (checkout,
   login, account, order tracking) — those aren't admin-specific, just
   generic enough that duplicating them into style.css would only invite
   drift. Relies on the CSS variables defined in style.css (--color-primary,
   --color-dark, --radius, --shadow, ...) — always load style.css first. */
