/* Card thumbnails.
 *
 * A portrait image scaled to the card width renders several times taller than
 * a landscape one, which stretches its card badly out of line with the rest of
 * the grid. Cap the rendered height rather than cropping the artwork:
 * max-height only bites when the natural rendered height exceeds it, so the
 * wide landscape thumbnails are left completely untouched.
