+"""Pet generation — base-draft → hatch pipeline.
+
+Public surface used by the gateway RPCs, the CLI ``hermes pets generate``
+command, and tests:
+
+- :func:`generate_base_drafts` / :func:`hatch_pet` — the two-step flow.
+- :class:`HatchResult`, :class:`GenerationError`.
+- :mod:`atlas` — deterministic frame extraction + atlas composition/validation.
+
+Image generation is delegated to the active reference-capable
+:class:`~agent.image_gen_provider.ImageGenProvider` (OpenAI gpt-image-2 or Krea);
+atlas assembly is fully deterministic so it's testable without any API calls.
