| Area | Recommendation |
|------|----------------|
| **TLS** | Use Certbot + Nginx plugin (`community.general.acme` Ansible module) |
| **Secrets** | Store DB passwords, secrets in **Ansible Vault** |
| **Updates** | Use `container_image: tag` with version pins (e.g., `v1.100.0`) |
| **Monitoring** | Add Prometheus metrics (`enable_metrics: true`) |
| **Coturn** | Deploy `coturn` (STUN/TURN) as separate container if needed |
| **Backups** | Backup `/var/lib/matrix-synapse` regularly |
| **Rootless Podman** | Use `podman user` namespaces + `podman system migrate` for portability |
