Also keep the full style for each image prompt (e.g. is it a painting or photo?):\n```\n{{ $json['Image Style'] || \"\"}}\n```\n\n---\n\n### GOAL\nCreate a concept for a 20–40 second video with consistent **visual style, tone, and lighting**, including:\n1. **5 detailed prompts** for AI-generated background images  \n2. **1 full narration text** (to be spoken by a narrator)  \n3. **4 sequential text segments** that align perfectly with the narration (each about the same length, representing the same story flow)  \n4. **1 short caption** for a social media post promoting this video  \n\n---\n\n### IMAGE PROMPT GUIDELINES\n- Each image prompt should clearly describe the **scene**, **style**, **setting**, **mood**, **lighting**, and **color tone**.  \n- All 5 images must feel visually and emotionally consistent.  \n- Choose an appropriate general lighting mood (e.g. bright and hopeful, dark and moody, colorful and energetic, monochrome and calm).  \n- Example structure for each image prompt:  \n  *“A cinematic photo of [subject/scene], [lighting type], [environment details], [emotion/feeling], [color palette/style].”*  \n- Style examples: “cinematic”, “soft focus”, “warm tones”, “volumetric light”, “dreamy atmosphere”, etc.  \n\n---\n\n### TEXT CREATION GUIDELINES\n- The full text should sound natural when spoken by a narrator.  \n- It should flow smoothly and build emotional or motivational impact.  \n- The 4 text segments should represent logical parts of the full narration (e.g. setup, reflection, climax, resolution).  \n- Keep tone consistent with the image prompts (motivational, dramatic, peaceful, etc.).\n- Do not use \"-\" or \"—\" (thinking / pause )\n\n---\n\n### OUTPUT FORMAT (JSON)\nReturn the result **only** as valid JSON structured like this:\n\n```json\n{\n  \"image_prompts\": [\n    \"Prompt 1\",\n    \"Prompt 2\",\n    \"Prompt 3\",\n    \"Prompt 4\",\n    \"Prompt 5\"\n  ],\n  \"full_text\": \"Complete narration text here.\",\n  \"text_segments\": [\n    \"Part 1 text\",\n    \"Part 2 text\",\n    \"Part 3 text\",\n    \"Part 4 text\"\n  ],\n  \"caption\": \"Short social media caption here.\"\n}\n```\n\nexample output:\n{\n  \"image_prompts\": [\n    \"A cinematic sunrise over misty mountains, golden light, hopeful tone, warm color palette\",\n    \"A lone runner on a foggy trail, morning light breaking through clouds, determination and focus\",\n    \"Close-up of hands tying running shoes, soft golden backlight, texture-rich realism\",\n    \"Runner pushing through rain, dramatic contrast lighting, resilience mood\",\n    \"A victorious silhouette at the mountain peak, glowing sky, triumphant energy\"\n  ],\n  \"full_text\": \"Every dream begins as a whisper.
