/* =========================================================
   ブログ記事（投稿詳細）読みやすさ改善
   - functions.php で is_singular('post') のときだけ styles.css の後に読み込む
   - 対象は single.php の本文まわりのみ。ヘッダー／フッター／CTA／関連記事／著者ボックスには影響させない
   - 著者ボックス（.saboxplugin-wrap）も .p-single__content の中にあるため、
     p・画像・リスト・表は「本文直下（>）」に限定している
   - 目次は Table of Contents Plus（#toc_container）
