The error block was a colour-only, visually-small dead end. Add
role="alert" so screen readers announce the failure, bump the message to
text-base and the recovery download link to text-sm with a py-2 tap
target — the only escape hatch, sized for the archive's older readers.

Addresses re-review: Leonie (a11y of the error state).
