/**
 * The virtual relays the container serves, and the only place their names are written down.
 *
 * zooid binds a config to a Host header and serves any number of them from one process, so a second
 * space costs a toml in docker/config and nothing else. The names are a union rather than a string
 * so that a scenario naming a relay that has no config fails to compile instead of hanging on a 404
 * from the dispatcher.
 *
 * Each host resolves nowhere, and `.test` is reserved by rfc 2606, so a url that escapes this
 * process fails to connect rather than reaching a host. transport.ts covers why the container is
 * told to call itself this rather than its loopback address.
