/**
 * BELAUN - News Archive & Single Post Styles
 *
 * お知らせ一覧・詳細ページ用。home.php / single.php は独立テンプレート
 * （Astra の get_header() を経由しない）なので、.ast-container 等の
 * 親テーマ wrapper との干渉は起きない前提で設計。
 *
 * アイテムの typography は TOP の .belaun-news__item と視覚的に揃える：
 * ・date: Meddon フォントで控えめに
 * ・title: Zen Kaku Gothic で主張
 * ・border-bottom で行を区切る
