 * The contact strip. Two things matter here and both were wrong.
 *
 * The cell must not be sized by the image. A grid item is stretched by default and the row is
 * sized by its content, so an <img> that has not decoded yet contributes nothing and the row
 * collapses, while free space is then handed back to the rows and blows them up again. The strip
 * resized itself under the reader's cursor every time a page of thumbnails arrived. Pinning the
 * item to its own 4:3 box, and reserving that box on the image before it decodes, keeps every cell
 * the same size from the first paint.
 *
 * And it has to be tall enough to work in: a snapshot here holds around twenty thousand samples,
 * which is not something anyone browses through two rows.
