/**
 * 子比自助广告位 - 前端样式（服务器端渲染架构）
 *
 * 设计思想（严格遵循开发方案 3.2）：
 * ========================================
 * 1. CSS Grid 布局系统
 *    - 使用 --per-row 自定义属性控制每行数量
 *    - 响应式断点（移动端/PC端）
 *
 * 2. 空位状态视觉设计
 *    - .is-empty 类标识空位
 *    - 虚线边框 + 招租提示
 *    - 悬停效果提示可购买
 *
 * 3. 已售状态视觉设计
 *    - 实线边框 + 阴影效果
 *    - 悬停放大/高亮
 *
 * 4. 性能优化
 *    - 使用 CSS 变量减少重复代码
 *    - 图片懒加载支持（loading="lazy"）
 *    - GPU 加速动画（transform）
 *
 * @package Zibll_Ad
 * @version 1.0.0
