# J621 — default deployment: frontend + backend + database on one Tailscale
# host, behind the nginx proxy service (no host nginx, nothing published on
# the host's ports).
#
#   cd deploy && cp .env.example .env    # fill in TS_AUTHKEY, SECRET_KEY, ...
#   docker compose up -d                 # or: docker compose -f compose.yml up -d
#
# Tailnet-only: no Funnel, so the service is reachable from your tailnet
# (https://<TS_HOSTNAME>.<tailnet>.ts.net) but not from the public internet.
# The nginx service routes /api, /admin, /static and /health to the
# backend and everything else to the SPA. Same origin, so no CORS needed.
