   2026-08-20 新規作成。他の型からの流用は無し。
   既知バグの回避:
     KB-001 ヒーローの文字は絶対配置にしない（背景画像＋通常フローのpadding）
     KB-002 モバイルの右寄せは .header-actions 側に持たせる
     KB-010 本文の最小は 12px（0.75rem）。それ未満を書かない
     KB-011 メニューを開いている間は body を固定し、高さは dvh で取る
     KB-013 表は .table-wrap で横スクロール。内側に overflow:hidden を置かない
     KB-014 320px でハンバーガーが押し出されないよう、ヘッダーの要素を縮める
