A node rebuild (tofu -replace / fresh OS) wipes host-level config Flux/Helm don't manage.
site.yml omits kube-vip.yml and vpn.egress.gateway.yml, so a re-provision missed the node-host
OpenVPN on k3s-dev-3 and dropped all egress-class=vpn pod traffic. Document the node-host layers
that must be re-run after any re-provision, and correct the stale author-only banner (these plays
are live).
