Fresh clones errored out on `ddev start` because the compose file's env_file: pointed at app/.env (gitignored). No env vars are actually required by the code — STATE_DIR is the only one and has a default. - Switch env_file to the path:+required:false form (Docker Compose 2.24+; bundled with DDEV) so missing app/.env is non-fatal. - Commit app/.env.example as documentation for contributors who do need overrides.
