+"""Local client for the local_responses sample.
+
+Posts to ``/responses`` using the standard ``openai`` SDK.
+
+Pass ``--previous-response-id <id>`` to continue a conversation by its
+``response.id`` (returned in the prior response).
+
+Start the server first (in another shell)::
+
+    uv run python app.py
+
+Then::
+
+    uv run python call_server.py
+
+The script sends two follow-up turns, each continuing from the previous
+turn's ``response.id`` as ``previous_response_id``. The third turn asks about
+information from the *first* turn only, so it also exercises session
+continuity across a rotating response id chain, not just a single hop.
