 * SWELL 親テーマの .post_content スタイル(濃紺の h2 ブロック・縞模様の h3 下線

 * 子テーマ側で上書きして editorial 風に整える。
 *
 * 適用範囲は `.single-post__body.post_content`(我々の single.php の本文ラッパ)

/* =========================================================
 *  H1 / H2 / H3 / H4 — editorial magazine スタイル
 *
 *  方針:
 *  - 「派手な色ブロック」を完全に排し、上品な細線+アクセントで階層を表現
 *  - 余白を大きく取り、本文を読み進めたくなるリズムを作る
 *  - SWELL 親テーマの強い装飾には !important で確実に勝つ
 *  - 集客記事の読了率を上げるため、視線を上から下へ自然に誘導
 * ========================================================= */

 *  ・本文よりひと回り大きいフォントで、明確に階層トップであることを示す
 *  ・下にミントソフトの長い罫線、左にミントディープのアクセント
 *  ・H2(上罫線+左短アクセント)とは「上下を反転した意匠」で対比
