# The cockpit is fronted by the external `backend` network's nginx-proxy as
# psyc.neuronetz.ai (point DNS for that name at the proxy host). mock-cert and
# the inference server stay internal — no VIRTUAL_HOST, reachable only inside
# `backend` by service name.
#
# WARNING: psyc has no built-in authentication. The reverse proxy / network
# perimeter is the security boundary. See docs/deploy.md.
