    Ratio stress test

    In this hackathon 96% of previews already land between 16:9 and 16:10, because YouTube demos and Devpost thumbnails are both near-widescreen, so the mixed-ratio problem is smaller than it looks. These four are real frames from the same demos, force-cropped to the extremes a future intake could throw at the grid. They test the layout, they are not submissions. Switch to Crop to see what edge-to-edge filling costs on the tall one.
