The banner was text-xs amber-200 — easy to miss in dark mode and near illegible in light mode. It now uses the app's warn-badge contrast pair (text-amber-600 dark:text-amber-300) at text-sm with a size-4 icon, stronger border/background, and medium weight, so it reads at a glance in both themes. The persistent variant gains a dismiss button that records the fingerprint acknowledgement; the post-switch notice stays undismissable because it announces a change that just happened.
