pigui 68ad014df0 Stop publishing a host port
`docker compose up` failed with "port is already allocated": 3000 was
taken by an unrelated project on the same machine. Publishing it was
never needed — in production the only thing that has to reach this
service is the reverse proxy, which does so over the compose network as
`landing:3000`.

`expose` replaces `ports`, and a commented `ports` block stays for the
cases that do want a host binding. LANDING_PORT is kept but re-labelled
as only mattering then.

Verified: the container binds nothing on the host, answers 200 with the
full page from another container on the network, and stays healthy —
its health check was always internal.

# Production. One service.
#
# The Pireon API is external — a separate deployment on the public internet, not
# part of this stack — so there is nothing here to orchestrate alongside the
# landing, and nothing to wait for on startup. What it does mean is that the
# container needs outbound HTTPS: the page is server-rendered, so every request
# it serves makes ten calls to `landing-api.pireon.dev` from inside the
# container. Behind a restrictive egress policy, that host has to be allowed or
# every page renders as if the API were in maintenance.
#
# NEXUS_TOKEN=… docker compose build # the build needs the private registry
# docker compose up -d
#
# Put a reverse proxy in front for TLS. It should pass the response headers
# through untouched: the app answers 503 with `Retry-After` while the API is in
# maintenance, and 404 for addresses it does not serve.
