Example output structure:\n\n[\n  {\n    \"prompt\": \"Sun-drenched poolside shot of the product on a marble ledge at golden hour, with soft shadows and warm tones.

GPT-4 analyzes the brand website to understand overall visual identity.\n5. A LangChain AI Agent uses both to generate 10 variation prompts.\n6. Each prompt is passed to Dumpling AI to generate a new ad image.\n7. All image URLs are logged in Google Sheets.\n\n"
