 * the small ones. In a two-column row a card is roughly 538px wide, so a 260px
 * box is about 2.07:1 while the photos are about 1.5:1, and background-size:
 * cover then cut roughly 30% off the top and bottom. On the SeePort hero that
 * kept the fireworks and lost the stage and the crowd.
 *
 * Sizing by ratio instead means the height follows the width, so at the default
 * 3 / 2 — the exact ratio of half the hero images and the median of all of them
 * — nothing is cropped at any viewport width.
