   Konon Acoustic — style.css
   全ページ共通スタイルシート

   【タイポグラフィ・余白の設計方針(シニア世代向け / W3C WCAG 2.2準拠)】
   - 文字サイズは相対単位rem。16px基準で必ず整数pxになる値だけを使う
     (WCAG 1.4.4: ブラウザの文字サイズ設定・200%拡大に追従するため)
   - 行間は単位なしの比率(WCAG 1.4.12: 1.5以上)。本文は2.0
   - 段落の間隔は文字サイズの2倍(WCAG 1.4.12)。本文18px → 36px
   - 1行の文字数は日本語で40字程度まで(WCAG 1.4.8)。本文幅 720px = 18px × 40字
   - 余白(margin / padding / gap)は4pxの倍数の整数px
   - 本文より見出しを十分大きくし、大小の差(めりはり)を付ける
