/* TechSnap 記事ページ共通スタイル（各記事インライン<style>の外出し。2026-08-12）
   ※ 2026-07に廃止した旧 css/article.css（.article-layout等の別クラス系）とは無関係の別物。
      こちらは現行インライン<style>と同一クラス・同一値をそのまま外出しした共通ベース。
   単品レビュー／スチューデント／楽天ボタンの全バリアントを内包する上位集合。
   未使用ルールが載っていても無害。新規記事は scripts/_TEMPLATE-single-review.html 経由でこの1本をlinkするだけ。
   .inline-review-link / .review-badge は css/style.css 側（サイト共通）にあるためここには持たない。 */
