Create a Debian Trixie headless network-appliance evaluation image with two
NICs, SSH, firewall, WireGuard, dnsmasq, nftables, and IP forwarding. Keep
WireGuard private keys and site addresses out of the recipe. Create a locked
operator account and require key-only SSH only after its public key path is
verified. Add a client VM scenario that proves DHCP/DNS behavior, routed
traffic, allowed management access, and denied traffic.
