 * ============================================================================
 * Wild Player 前端标准化 - 公共样式 (Frontend Common)
 * ============================================================================
 *
 * 文件用途：
 *   - 所有前台页面共享的通用样式
 *   - 组件级样式（卡片、按钮、表单、空状态、加载状态等）
 *   - 响应式工具类
 *   - 动画/过渡效果
 *
 * 使用方式：
 *   在 layout.html 的 {block name="css"} 中通过 <link> 引入
 *   或在页面特定样式中 @import 此文件
 *
 * 依赖：
 *   - Bootstrap 4.6.2 (必须先加载)
 *   - frontend-variables.css (提供 --primary 等 CSS 变量)
 *   - design-system.css (提供 .top-nav, .front-footer-info 等基础样式)
