/* ============================================================
   self·medi — 登録販売者の視点で選ぶセルフケアメディア
   設計方針:
   1. 信頼が主役: ブランド色は「薬局の深緑」。構造・導線・本文アクセントはすべて緑系。
   2. カテゴリ色は「分類の記号」専用: ピンク=スキンケア等は ラベル/サムネ面 のみに限定。
      構造(見出し/CTA/表/パンくず)には使わない。
   3. 商業ゾーンの分離: アフィリエイト導線は編集コンテンツと明確に別の見た目(PR枠)。
   4. 注意情報は琥珀色で独立: warning-box は緑ともピンクとも混ざらない。
   5. 見出しは明朝(Shippori Mincho)で「編集された媒体」の骨格を作る。
