   Uniform cards on purpose. The source screenshots have very different
   natural aspect ratios, so letting them size themselves produces a ragged
   grid with no shared baseline. Each is cropped to a fixed 16:10 window
   anchored to the top of the image, which is where a UI screenshot carries
   its identifying detail. The full, uncropped image is one click away in the
