/* shell.css — shared header + footer shell (nx-)
 *
 * Loaded by layout.php for every public page, and by admin.php / login.php so
 * the shared header/footer they include still render. Self-contained: every
 * token has a fallback, so it does not require nexera.css or components.css.
 * Replaces the Bootstrap navbar/footer rules that used to come from
 * cards.css + compat.css.
