/* ==========================================================================
   dads.css — デジタル庁デザインシステム（DADS）HTML版からの部分導入
   出典: C:\main\private\90_公開サイト\dads-html\ (MIT License, Digital Agency)
   導入部品: breadcrumb / toc (link・list依存) / disclosure
   方針: global.css全体は持ち込まず使用変数のみ抽出。フォント・キーカラーは
         サイトのトーン（土色系）に上書き。末尾に「サイト適合上書き」あり。
   導入日: 2026-07-18
