/* page-loader.css
 * Full-screen overlay that blocks interaction during form submission / approval actions.
 * Trigger via showPageLoader() / hidePageLoader() defined in page-loader.js.
 * Auto-wired to every POST form that does NOT use data-swal-confirm (see page-loader.js).
 * For programmatic form.submit() calls, invoke showPageLoader() explicitly beforehand.
