curlimages/curl sidecar (profile stack, depends_on healthy): restores duo slot caches on boot (pre-loads both duo servers) and auto-saves every 300s while loaded. No manual duo-warmboot.sh calls needed; the script remains for ad-hoc use. Snapshot tracks the latest real session; prefix matching (--cache-reuse) handles divergent new sessions.
