Repurpose YouTube videos to social media posts with RSS, Dumpling AI, Airtable

### 🖼️ Generate & Upload Platform-Specific Content

Each branch in this section handles one platform (Instagram, Facebook, or LinkedIn). Here's how they work:

1. **AI Image Generation (Dumpling AI)**  
   - Each branch uses a specific image prompt (from earlier GPT output) to generate a custom AI image using Dumpling AI's `generate-ai-image` endpoint.

2. **Save Content to Airtable**  
   - Posts generated for each platform are saved in Airtable using their respective nodes (`Instagram`, `Facebook`, `LinkedIn`). Platform labels and post text are included.

3. **Attach Image to Airtable Record**  
   - Once the image is generated, the matching image URL is patched into the correct Airtable row (as an attachment), keeping content and media organized under one record.

💡 *All three branches follow the same flow structure, ensuring consistent results across platforms.*
