/**
 * YiwuPage Mobile UX Enhancement — Phase 13.4
 * themes/yiwupage/assets/css/mobile.css
 * 
 * 加载方式: media="(max-width: 768px)" — 仅手机端加载，不增加PC负担
 * 优先级: 在各页面CSS之后加载，覆盖PC/平板断点样式
 * 
 * 改进项目:
 * - 底部快捷导航栏 (검색/기업디렉토리/기업등록)
 * - Header 搜索栏常驻显示
 * - 企业详情页底部 CTA 增强 (문의하기 + 전화)
 * - Safe-area 适配 (iPhone 刘海屏/底部横条)
 * - 首页移动端精简 (Stats 横向滚动)
 * - 分类/搜索/市场页面移动优化
 * - 触控友好 (44px+ 点击区域)
 * - 图片 CLS 优化 (aspect-ratio)
 * - 滚动优化 (-webkit-overflow-scrolling)
