Wraps the active :class:`~agent.image_gen_provider.ImageGenProvider` with the two things sprite generation needs that the agent-facing ``image_generate`` tool doesn't expose: **N variants** (loop) and **reference-image grounding** (so each animation row stays the same character as the chosen base). Reference grounding only works on providers that support it — currently OpenAI ``gpt-image-2`` (image edits) and Krea (style references). We resolve to one of those and surface a clear, actionable error otherwise rather than silently producing an ungrounded, drifting pet. ) annotationsN) dataclass)Path)nousopenai openai-codex openrouterkreaz Nous Portal OpenRouterOpenAIzOpenAI (Codex)Krea)rr rrr zdict[str, str]_PROVIDER_LABELSctjjddjj }|t vr|SdS)aOptional QA override to force a pet-gen backend. `HERMES_PET_IMAGE_PROVIDER=` (e.g. `openrouter`) bypasses the normal active/default provider resolution for pet generation only.

We *ask* for a transparent background, but fall back to an opaque generation (cleaned up downstream by the chroma-key pass) on models that reject the flag.
