/* ============================================================
   とーんと日本橋 サイト内 横断検索 結果ページ（search.php）
   対象: 検索窓(tn-hero-search) ＋ 結果(tn-search / tn-sr-*)
   方針: AI生成感排除マニュアル準拠 / トップ改修(redesign.css)と同トーン
   - 墨色 #1a1a1a / 茜 #b8242b / 単色 / 角丸最小 / 英字eyebrow・装飾下線・
     border-left・::before罫線・::after矢印 なし
   - これらは .l-mainContent 直下（.post_content 外）に出るため SWELL本文
     セレクタ(0,1,1)との競合は無い。リンク色は要素側で明示して親に勝つ。
