/**
 * Service Template - Glass UI Control System
 * 
 * ==========================================================================
 * AI AGENT & DEVELOPER INSTRUCTIONS / 設計規約
 * ==========================================================================
 * このスタイルシートは、Tomeoki/Anotaベースのグラスモーフィズム（すりガラス）UI
 * を構築するための再利用可能なコンポーネント群を定義しています。
 * 
 * [基本ルール]
 * 1. プレフィックス: コンポーネント用クラスはすべて `g-` で始まります（例: `g-btn`, `g-card`）。
 * 2. 背景との調和: 背景画像の上に半透明カードを重ねる前提のため、半透明白(ダークモードは半透明暗色)
 *    と backdrop-filter: blur() を多用しています。
 * 3. セマンティクス:
 *    - ボタン: `.g-btn` + `.g-btn-primary` / `.g-btn-secondary` / `.g-btn-outline` / `.g-btn-danger`
 *    - 入力欄: `.g-input`, `.g-select`, `.g-textarea`（`.g-form-group` 内に配置）
 *    - カード: `.g-card`（必要に応じて `.g-card-header`, `.g-card-body`, `.g-card-footer`）
 *    - バッジ: `.g-badge` + `.g-badge-success` / `.g-badge-warning` / `.g-badge-danger` など
 *    - 表: `.g-table`（`.g-table-wrap` で囲む）
 *    - アラート: `.g-alert` + `.g-alert-info` / `.g-alert-success` など
