"""Phase 3 comparison models behind one captioning interface (ADR-019).

Every compared model (the project's CNN + Transformer and the pretrained
Hugging Face baselines) captions images through :class:`Captioner`, so the
comparison runner and the latency benchmark share one call path and one
caption normalisation.

``transformers`` and ``torch`` belong to the optional ``[hf]`` extra and are
imported only inside :meth:`HFCaptioner.load`. Importing this package loads
neither of them, and doesn't load TensorFlow either.
