Add a large amber alert-triangle icon to the 'keep your config backed up offline' banner and a close (x) button in its top-right. Dismissal is stored in localStorage (libreportal:backup-config-warning-dismissed) — a per-browser UI nudge, not server config — and hides both the banner and its divider until cleared.
