/* inheritee landing page (Issue #547)
   - 見た目は /design で合意したキャンバス（PC 1440px / スマートフォン 390px）に合わせる
   - ライト固定（ダークモードは対象外）
   - 方向は論理プロパティのみ（RTL 対応のため left / right / margin-left を使わない）
   - Web フォントは読まない。システム書体のスタックで明朝／ゴシックに近づける
   - レイアウトのブレークポイントは 1 本（max-width: 767px）。中間の幅は auto-fit の折り返しで吸収する
   - ほかにヘッダーのページ内リンクの表示だけを 1099px で切り替える（言語によって入り切らないため） */
