/*
 * Grid banners: an image card the exact size of a video card.
 *
 * The card is a grid item like any video card, so the row's height comes
 * from its neighbours (align-items: stretch) and the image fills it. The
 * aspect-ratio is only a floor for a row made of banners alone; 4:3 is a
 * little shorter than a video card, so it never makes a mixed row taller.
