 * 最終更新: 2025年8月1日
 * バージョン: 2.2.0（構造最適化版）
 * 
 * クイックカスタマイズガイド:

 * - 8,000行以上をSCSSミックスインで最適化
 * - グラスモーフィズムデザインシステム
 * - レスポンシブモバイルファーストアプローチ
 * - ダーク/ライトテーマサポート
 * - 印刷最適化レイアウト
 * - クリップボードコピー機能
 * 
 * 利用可能なミックスイン:
 * @include flex-center;        // 完全中央配置
 * @include text-primary(0.8);  // テーマ対応テキストカラー
 * @include glass-effect(light); // グラスモーフィズム効果
 * @include common-transition(); // 統一トランジション
 * 
 * テーマカラー推奨値:
 * ミステリー: 250 | ホラー: 0 | ファンタジー: 280 | SF: 200

 * ファイル構成:
 * 1. CSSカスタムプロパティ（テーマカラー、間隔、タイポグラフィ）
 * 2. SCSS変数とミックスイン（再利用可能パターン）
 * 3. ベーススタイル（レイアウト、タイポグラフィ、フォーム）
 * 4. コンポーネントスタイル（カード、ボタン、モーダル）
 * 5. コンテンツスタイル（ハンドアウト、NPC、シーンテーブル）
