"""cryptpad — backup/restore stage (D2): write a marker into the backed-up cryptpad_data volume,
backup, mutate, restore, assert the restored state matches the pre-mutation (backed-up) state.

The cryptpad `app` service is labelled `backupbot.backup=true`, so its volumes (incl. cryptpad_data)
are backed up. Marker is checked via `exec_in_app` (data isn't HTTP-served)."""
