Host provisioning for the single-server production target: SSH + firewall
hardening (nftables allowlist), k3s node registration, bare-metal Stalwart
install with systemd units and TLS cert-sync from the cluster secret, and
Restic encrypted backup/restore (primary + DR) with timer units. Host-specific
secrets live in config.env (gitignored); config.env.example is the template.
Also gitignores MemPalace per-project files.
