   型15 塗装・建物改修の専門店 ／ 方向B「顔が見える安心型」
   2026-08-20 新規作成。型3（暮らしの情景型）からの流用は無し。
   見た目の言語をはっきり分けている:
     型3  … 明朝見出し／角2px／影なし／罫線で仕切る／写真が主役
     型15 … 太ゴシック見出し／角10px／やわらかい影／丸い顔写真／文章が主役
   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
     KB-002 モバイルの右寄せは .header-actions 側に持たせる
     KB-010 最小フォントは 12px（0.75rem）
     KB-011 メニューを開いている間は body を固定
     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 380px 以下で電話を畳み、ハンバーガーを画面内に収める
