1. One subject you can name in two words at 168 px wide.
2. Five words or fewer of text.
3. Faces at 28-40% of the height.
4. Light on the faces matches the light in the scene.
5. Nothing in the bottom-right timestamp corner.
6. One accent colour, on one word.
7. No AI tells: warped hands, garbled micro-text, plastic skin.
