Automated Story & Image Workflow

I need a reusable n8n workflow that turns a user-provided prompt into a complete short story and a matching cartoon-style image. The flow should:

• Accept plain-text input from a chat node
• Pass the prompt to an LLM node (OpenAI or a similar text generator) and return a concise short story
• Feed the story’s key visual description into an image model able to output a single cartoon-style illustration (Stable Diffusion, DALL-E, or any service you can call from n8n)
• Save both assets to cloud storage and send back the image link plus the generated story to the originating chat thread

Acceptance criteria
• Story length: 250–400 words, coherent beginning-middle-end
• Image resolution: at least 1024×1024 PNG, clearly reflecting the story’s theme
• Entire process runs hands-free once the initial prompt is received, with errors logged in n8n’s execution history

Provide the .json workflow file, brief setup instructions, and notes on any credentials or environment variables I must add before deployment.
