Why this prompt works
Thumbnails compete at small sizes, so the prompt demands a single bold focal subject and high contrast over fine detail.
A 16:9 frame with space for title text is specified because that's how thumbnails are actually used.
Low contrast and clutter are excluded since they're why most thumbnails disappear in the feed.
