   样式隔离契约（重要，请严格遵守）
   ------------------------------------------------------------
   ▸ 默认区块（无 @media 包裹）= Web 端（≥769px）基线
       - 改 Web 端时只动这里
       - 禁止在此处加任何只服务移动端的样式
   ▸ @media (max-width: 768px) { ... } = 移动端（≤768px）专属
       - 改移动端时只动 768 媒体查询块内的规则
       - 禁止修改默认区块的属性值；如需差异化，用 768 媒体查询块覆盖
   ▸ @media (max-width: 980px) 等其他断点 = Web 端的响应式微调
       - 属于 Web 范畴，调整移动端时不要动
   ▸ 新增移动端独有的 class/规则，统一写在文件末尾的 768 块内
