Make sure the prompt is concise but expressive, suitable for use inside a JSON payload or passed into an image generation API. All key elements must remain: characters, objects, text styling, and background mood — but the format should be clean, compact, and system-friendly.\n- Format the output as a single line of plain text, using escaped double quotes (\\\") where needed, suitable for inclusion in a JSON string without formatting issues."
