deploy/stages.md walks through the Test/Int setup on 188.245.116.44:
stage directories and .env values, reverse-proxy vhosts (incl. the
/collab WebSocket route needed from M3), act_runner registration,
deploy user with per-stage SSH keys, and registry access. Root steps
are marked and executed together with the repo owner.
