`public.domain` is the whole switch. Empty — the default, and what compose, CI
and a laptop cluster use — renders nothing new and leaves every manifest as it
was. Set it and templates/edge.yaml adds a Caddy deployment that gets its own
certificates from Let's Encrypt and proxies the five browser-facing hostnames to
the ClusterIP services, so a public deployment doesn't use their NodePorts at
all.
Caddy rather than an ingress controller because the four portals already run
caddy:2-alpine (ADR-0034, whose ceiling note called exactly this out): no new
dependency, no cert-manager, no CRDs, no Ingress objects for five hostnames that
never change. The Fedora host keeps only a layer-4 forward of 80/443, because
the public IP is there and nothing in the cluster can claim it.
KC_HOSTNAME and the portals' config.json now both come from `big.keycloakUrl`,
so the issuer a token carries and the authority the BFF discovers are one string
by construction (ADR-0010) rather than by two templates agreeing.
