   セクション見出しタイポグラフィ（編集デザインルール）
   -----------------------------------------------------------------------------
   ■ 構造 … 1行目＝【章】ラベル、2行目以降＝本文。HTML は行ごとに .section-heading__line。
   ■ 改行 … 行内はカラム幅いっぱい（max-width:100%）＋ text-wrap: pretty（balance は和文で不自然な改行になりやすい）。
            禁則は line-break: strict / word-break: normal（欧文式の mid-word 改行を避ける）。
   ■ サイズ … clamp でモバイル→デスクトップ連続スケール。1行目ラベルは本体の約72〜78%。
   ■ モバイル … 行間やや広め、行幅 18〜21em 相当に抑えて視線の往復を短くする。
   ■ デスクトップ … 行幅 26〜30em、行間ややタイト、字間はやや詰める。
   ■ 修飾 … --editorial（本文セクション h2）、--on-dark（第3章）、--cta（CTA）、--hero（表紙）、
            --sub（中見出し）、--toc / --funnel / --inline は従来どおり用途別に微調整。
