- Added generate_thumbnail_prompt(notes) to thumbnail_utils.py - yt_poster.py now reads notes.txt (if present) from the clip directory - Uses content to generate brand-aligned OpenAI prompt for future AI thumbnail generation - Fallback: generic description if notes.txt is missing - Prompt is printed for now; image generation hook is pending
