  "summary": "The article discusses the engineering challenges of designing a prompt contract for a photo-to-coloring-page app, using the Picture To Coloring Page project as a concrete example. It highlights the importance of separating different controls, such as art style, shape language, line rules, and detail level, to avoid conflicts in the generated output. The author emphasizes the need to make exceptions explicit, such as handling tracing styles differently from ordinary coloring output, to ensure the model follows the desired instructions. The article also emphasizes the role of the reference photo in guiding the output, preserving the subject's identity and composition while allowing style to simplify or exaggerate forms.",
