+# No `container_name` and no anonymous/random host port: `app`'s host port is a
+# stable, project-specific mapping (4173) that will not collide with the gate
+# running this stack under a `-p <project>` prefix alongside a live deployment —
+# both instances share the same compose.yaml, isolated by project name, and the
+# gate/orchestrator polls this exact port for the health check (toolchain
+# health_url must match).
