We self-delegate _acme-challenge.unkin.net into an acme.unkin.net zone we serve, so cert-manager can solve Let's Encrypt DNS-01 over RFC2136/TSIG. That needs a publicly-reachable authoritative BIND, separate from the internal estate. - Add app bind-external (base + au-syd1 overlay) and register it in the platform ApplicationSet and AppProject destinations. - Add BindCluster bind-external: authoritative-only, recursion off, no forwarding, transfers denied except the keyed catalog/zone AXFR; 2 replicas; primaryService is a dmz-pinned PureLB LoadBalancer (198.18.199.53). - Add BindZone acme.unkin.net (primary, dynamicUpdate) and BindTSIGKey certmanager (hmac-sha256), whose Secret reflects into the cert-manager namespace for the rfc2136 solver.
