Thumbnail critique: score 0-100, readability at feed size, text, contrast, clickbait risk, fixes. Looks at a thumbnail image URL (jpeg, png or webp, up to 4 MB) the way a viewer sees it at feed size and returns a 0-100 score, whether it reads when small, the exact text in it, contrast, focal point, face and emotion, clickbait risk, strengths and concrete fixes. Pass the video title to check title and thumbnail work together.
