/* ============================================================
   誉邦官网 忠实复刻版 —— 响应式覆盖层
   基底为原站 6 个 CSS（style/common/buttons/gun/dh/demo），本文件只负责：
     1) 修掉原站的结构性问题（quirks mode / 无 viewport / 固定 1200px）
     2) 在 <1200px 时做流式降级，<768px 时切换为汉堡抽屉导航
     3) 新增组件（搜索、占位图、面包屑）的样式
   原则：>=1200px 时视觉与原站逐像素一致，不改动任何原有观感。
