   i会计 iAccounting — 样式表
   ============================================================

   两套外壳，视觉刻意拉开距离：

     客户 Portal   浅色 + 科技蓝，像面向客户的财务 SaaS 产品
     内部 Admin    深色侧边栏，像内部管理系统

   看起来像的话，早晚有人在客户界面上做全平台的判断。

   ── 关于虚线 ────────────────────────────────────────────────
   这份文件里**一处 dashed 都没有**，这是刻意的。
   上传区原本用 `border: 2px dashed` 做拖拽提示，而它挂在一个
   <label> 上（默认 display:inline）；inline 盒里放块级子元素会被
   浏览器拆成多个行内片段，每个片段各画一段自己的边框 ——
   于是卡片左下角出现一条竖虚线加一个 L 形折角。

   加 display:block 能修好，但只要虚线还在，这类问题就还有复发的
   土壤（将来任何人改了 display、加了 float、套了 flex 都可能重现）。
   所以这次直接换掉表现手法：实线 + 内层浅色面板 + 悬停变色，
   **不依赖任何 dashed**。没有虚线，就不会有虚线残影。
