+# backend on :8000 serves the built web UI itself (no separate Vite), so this
+# only starts the memory service + backend. The AI (Ollama) does NOT auto-start
+# — turn it on from the UI's Start AI button. Closing the app window shuts the
+# services back down (matches the launcher's "closing the window shuts it down").
