/**
 * style.css — OpsLoadout カスタムスタイル
 *
 * このファイルは、Tailwind CSSで提供されない
 * カスタムコンポーネントとユーティリティを定義します。
 *
 * アーキテクチャ:
 * - Tailwind CSS (CDN) をベースとして使用
 * - カスタムコンポーネントで不足部分を補完
 * - レスポンシブデザイン（モバイルファースト）
 * - アクセシビリティ対応（focus-visible、ARIA）
 *
 * セクション構成:
 * 1. Global Styles (Scrollbar, Transitions, Focus, Body)
 * 2. Layout Components (Header, Main, Footer)
 * 3. Controls Section (Filters, Buttons, Inputs)
 * 4. Form Components (Input, Select, Checkbox)
 * 5. Button Components (Primary, Secondary, Danger)
 * 6. Badge Components (Warning, Danger)
 * 7. Modal Components (Backdrop, Content, Header)
 * 8. Item Table (Responsive Grid Layout)
 * 9. Saved Checklists Section
 * 10. Print Styles
 *
 * デザイン原則:
 * - モバイルファースト: 小さい画面から設計
 * - プログレッシブエンハンスメント: 基本機能から拡張
 * - アクセシビリティ: キーボード・スクリーンリーダー対応
 * - パフォーマンス: トランジション最小化、GPU加速
