"""Example 4 — talk to the server over plain HTTP (OpenAI-compatible).

Use this when the caller is NOT this Python process: another language, a tool,
or a different machine. The server speaks the OpenAI Chat Completions shape.

Install requests first:

    pip install requests

Start the server in another terminal:

    python app.py

Then run this from the project root:

    python examples/04_server_http.py

Each response includes a `conversation_id`; send it back in the next request's
body to continue the same thread.
"""

# ignores `model` and keeps the original.
