/* ==================================================================
   启动缓冲页（Splash）· 网页端共用样式
   ------------------------------------------------------------------
   · 独立文件：页面只加一行 <link rel="stylesheet" href="/splash.css">，
     不改动各页面自己的样式文件（避免与同事的改动冲突）
   · 覆盖整屏（position:fixed + 极高 z-index），叠在应用之上显示，
     背后的页面照常加载；逻辑见 /splash.js
   · 排版以手机优先：主标题 1~2 行、卖点竖排、无横向滚动
