/* ==========================================================================
   common/auth-tip.css  —  「登录后才能操作」蓝色提示弹窗
   --------------------------------------------------------------------------
   配套 common/auth-tip.js（window.dlAuthTip）。目前用在 /download.html：
   未登录点「下载」时弹这个窗，点「去登录」才跳登录页，登录后自动回到本页。

   为什么不用 v10 的 showMessage（.alert 那种）：它是一小条 toast，用来
   解释「为什么不能下载」太重、也不够显眼；这里做成居中弹窗 + 遮罩。

   配色沿用站点主色 --Original(#0056fe) 那一套蓝，与「去登录」按钮同色。
   所有类名带 dl-auth- 前缀，避免和主题里已有的 .alert / .modal 冲突。
