+// Debug configurations for Dograh contributors.
+//
+// Prerequisites:
+//   - Python interpreter selected in VS Code (devcontainer sets this
+//     automatically; otherwise pick `./venv/bin/python` via the
+//     "Python: Select Interpreter" command).
+//   - api/.env exists (copy from api/.env.example, or api/.env.devcontainer
+//     is created automatically by the devcontainer post-create script).
+//   - api/.env.test exists for the test configurations (copy from
+//     api/.env.example and point at a throwaway database).
+//
+// All Python configs set justMyCode=false so the debugger steps into
+// library code (useful for tracing through pipecat/fastapi/etc.).
