Gluetun cannot do PIA over WireGuard (upstream unsupported; live "provider name
is not valid for Wireguard"). Operator approved OpenVPN-UDP and ADR-0013 was
amended in the spec. This aligns the impl:
- platform/kustomization.yaml: re-enable `- vpn-egress` (Phase 3, OpenVPN-UDP)
- gluetun-gateway.yaml: clean stale WireGuard comments (header, image note,
VPN_TYPE/creds comments); config already VPN_TYPE=openvpn
- README.md: PIA-over-OpenVPN, status=enabled, steering iface wg0 -> tun0
- DECISIONS-LOG.md: disk/drive incident (k3s -> NVMe; failing Seagate) + Phase-3
OpenVPN resolution
Stale WireGuard comments inside the operator's encrypted pia-credentials.sops.yaml
header left untouched (editing breaks the SOPS MAC; cosmetic).

gluetun-gateway.yaml referenced ${PIA_REGION}/${CLUSTER_POD_CIDR} but they were never defined
in cluster-vars, and the README didn't say where to set them. Add both to
clusters/base/cluster-vars.yaml (ConfigMap data:, string values, Flux postBuild substitution).
CLUSTER_POD_CIDR is 10.0.0.0/8 (Cilium cluster-pool — pods get 10.x, confirmed live), NOT the
k3s 10.42.0.0/16 I'd assumed. README now names the file + format + per-env override + PF-region note.

Per ADR-0013: platform/vpn-egress/ = a single shared Gluetun gateway (PIA over WireGuard,
built-in kill-switch FIREWALL=on, native port forwarding), namespace (non-app, NET_ADMIN +
/dev/net/tun), control-API Service, and a pre-wired (commented) pia-credentials SOPS line.
Defined the PIA secret location (platform/vpn-egress, keys username/password → OPENVPN_USER/
OPENVPN_PASSWORD) and updated the SOPS template accordingly.
NOT wired into platform/kustomization.yaml (Phase 3, author-first) — deploy needs PIA creds +
validation of the egress-steering mechanism (Cilium Egress Gateway → the Gluetun node's wg0;
documented in README with options + a fail-closed rationale, deliberately NOT committed as an
untested CiliumEgressGatewayPolicy). WireGuard chosen (UDP, protocol != TCP); PIA supports it on
all regions and the secret stays username/password.
