牛来风格图片生成

Use the runtime's image-edit tool for an existing still and its image-generation tool only for a new scene. Treat the task as style-transfer when an edit target exists and as stylized-concept for a new scene.

Choose the mode

• Default to niulai-film-3d: rough low-budget 3D observed in public film frames.
• Use niulai-poster-ink only when the user explicitly asks for the water-ink poster. Never mix the poster with the film-frame references.
• Describe the result as matching the observed public-frame visual grammar, not as an official art specification.

Read style-spec.md before authoring the prompt. Read evaluation-rubric.md before judging any output.

Prepare inputs

1. Label the edit target as Image 1.
2. Select two style references from assets/style-reference/ that cover face and body. The image tool accepts at most three inputs total.
3. If a source still is wider than about 1600 px, resize a working copy first. Oversized stills fail.
4. Preserve the target's character count, positions, action, clothing-color roles, key props, and camera crop unless the user asks to change them.
5. Remove source logos, titles, dates, subtitles, and watermarks from the output.
6. If a still is blocked by moderation, stop that still and switch to another adult scene. Do not paraphrase to retry. Prefer stills of adults; skip group shots of children.
