"""Question generation package.

The main entry point is :class:`~deeptutor.agents.question.pipeline.QuestionPipeline`.
Lightweight names (``FollowupAgent``, ``QuizTemplate``, ``QuizPair``, etc.)
are resolved lazily so callers that only need one symbol don't eagerly
import the full pipeline + its LLM dependencies.
