/* ============================================================
   BuildLab — 设计系统
   规矩落地：
   1) 边框只套一层       —— 全局只有 --line 这一层描边，嵌套层级靠背景色差
   2) 圆角内外同心       —— --r-o 外层，内层恒为 calc(var(--r-o) - var(--pad))
   3) 分屏防翻车         —— 全用 minmax/auto-fill/clamp，无固定宽度
   4) 打中文不误发       —— 见 ui.js safeEnter
   5) 翻记录不被拽       —— 滚动容器独立 + overscroll-behavior: contain
