   宋氏宗亲平台 · 移动端设计系统（Mobile-First）
   ----------------------------------------------------------
   目标：H5 手机端 + 微信小程序端统一视觉语言
   对标：世界顶级姓氏/族谱平台（Ancestry / MyHeritage / 族谱网）
   设计原则：
   1. 移动优先 —— 所有组件先为手机设计，再向上增强
   2. 触摸优先 —— 命中区 ≥ 44px，无 hover 依赖
   3. 安全区适配 —— env(safe-area-inset-*)
   4. 一屏一焦点 —— 单列流式布局，减少横向滚动
   5. 手势友好 —— 滑动、下拉刷新、上拉加载
