 *
 * Deliberately NOT a block stylesheet. blocks/archive-listing/style.css would
 * only load where that block is on the page, and the same cards render on the
 * topic, category, tag, date and author archives, where the block never
 * appears. Deliberately not css/content.css either: that file owns the core
 * blocks and excludes [class*="wp-block-sws-theme-"] on purpose.
 *
 * Enqueued conditionally from functions.php (is_home / is_archive / is_search)
 * and not passed to add_editor_style(): the block draws a static placeholder in
 * the editor, so there are no cards to style there.
