 * 【リファクタリング基準】CSSファイル用（コメント行は行数カウントから除外）
 * ----------------------------------------------------------------
 * 現在の実コード行数: 約300行（コメント除く）
 * 判定: ✅ 完璧（500行未満）
 * ----------------------------------------------------------------
 * 基準（CSSファイル専用）:
 *   1. 500行未満 → 完璧 ✅
 *   2. 800行未満 → 問題なし ✅
 *   3. 1200行未満 → 注意喚起。リファクタリング要検討 ⚠️
 *   4. 1200行以上 → リファクタリング必須 🚨

 * このファイルから以下を分割しました:
 *   - theme_variables.css: CSS変数定義（:root, data-theme）
 *   - layout.css: レイアウト構造（メインコンテナ・サイドバー・ヘッダー・ツールバー）
 *   - luxury_components.css: ラグジュアリーテーマコンポーネント
 * ================================================================================
 *
 * This is a manifest file that'll be compiled into application.css.
 *
 * With Propshaft, assets are served efficiently without preprocessing steps. You can still include
 * application-wide styles in this file, but keep in mind that CSS precedence will follow the standard
 * cascading order, meaning styles declared later in the document or manifest will override earlier ones,
 * depending on specificity.
 *
 * Consider organizing styles into separate files for maintainability.
