traefik.host.match renders a domain as a Traefik router rule. Traefik v2 resolves HostRegexp
through gorilla/mux, where the pattern is a {name:regexp} template and every literal segment is
quoted, so a wildcard label is spelled out as a named group rather than a raw regexp. The group
matches a single label, mirroring both DNS and Kubernetes Ingress wildcard hosts.
