/**
 * DX促進支援ページ専用スタイル
 *
 * @package zephyr-child
 * @file    collaceptor-dx-support/dx-support.css
 * @version 2.0.0 (Prototype-aligned)
 *
 * 設計方針:
 *   - すべてのスタイルを .dx-support-page スコープに限定し、Zephyrテーマと衝突を回避
 *   - CSS変数で色・フォント・余白を統一管理
 *   - モバイルファーストでメディアクエリを段階的に拡張
 *   - 既存の [dx_tool] ショートコード出力には影響を与えない
