# This is deliberately NOT compose.yaml: that one bind-mounts ./postgres-data
# (state would leak between runs) and reads the gitignored container.env. Here
# the database is thrown away on every run and all env is inline, because
# .gitignore ignores `*.env` and a new env file would be silently untracked.
#
# Always invoke through scripts/e2e.sh, which adds the flags that actually
# guarantee a clean database (see the `db` service).
