Notes

Automated pipeline: (1) script-writer outputs key visual moments, (2) image.md generates 5-10 thumbnail variants using style library templates, (3) optimizer scores variants (text readability, face prominence, contrast, emotion), (4) optionally A/B test via YouTube API or manual upload. Uses Nanobanana Pro JSON for consistent brand style across variants. References content/production/image.md and content/optimization.md.
