 * PropOffice component does. The only literals here are neutral fallbacks for a
 * site that has not run the runtime layer at all.
 *
 * 🚨 NOTHING HERE STYLES A PROPERTY CARD. Not one selector reaches inside
 * `.po-pc`, and the grid the cards sit in is the Property Card's own. The cards
 * were designed before this component existed and are unchanged by it.
