 Set `LLM_PROVIDER` + the matching key (or just `LLM_API_KEY`). Override `LLM_BASE_URL` / `LLM_MODEL` for any other compatible endpoint. The right auth header (bearer vs api-key) is chosen automatically. Quiz answers and chat responses surface a model's `reasoning_content` when available, but it isn't required.
