   * Type scale — ジャンプ率設計
   *
   * ★ Oswald Bold (condensed display) 補正について:
   *   Condensed フォントは同 px でも文字の面積が通常より大きく見える。
   *   Oswald 700 は特に字面が大きく、視覚上のサイズが数値の 1.15〜1.2 倍に感じられる。
   *   そのため、通常フォント想定のジャンプ率計算値より 15〜20% 小さい数値を設定する。
   *
   * body ≈ 17px 基準 / 視覚補正後のジャンプ率目安:
   *   --fs-h2   max 1.6rem  (25.6px) → ratio ≈ 1.5  セクション副見出し
   *   --fs-h1   max 2.2rem  (35.2px) → ratio ≈ 2.1  セクション主見出し
   *   --fs-hero max 2.75rem (44px)   → ratio ≈ 2.6  ヒーロー大見出し
   *               Oswald 補正後の視覚ジャンプ率 ≈ 3.0〜3.1（上品な強さ）
   *
   * プレミアム/ウェルネス系の目標: 視覚ジャンプ率 2.8〜3.2。
   * 数値ジャンプ率 3.5+ はスポーツ・セール系の印象を与える。
