/* ==========================================================================
   耀光极域 · 统一按钮与交互状态（美化层）
   --------------------------------------------------------------------------
   设计原则（参考成熟站点如小米官网的做法）：
     1) 去掉“上浮位移 + 大范围光晕”，改为克制的底色/描边过渡；
     2) 主操作实色、次操作描边、破坏性操作仅用红色描边 —— 颜色不再堆叠；
     3) 表格内动作按钮统一高度/圆角/字号，成组排列；
     4) 文字型入口（登录等）用下划线动画，胶囊按钮只留给最重要的一个动作；
     5) 配色沿用站点原有色板：深蓝 #0a1f3d / 亮蓝 #0099ff / 青 #12c6c6。
   本文件在各页面的 <head> 末尾引入，因此规则顺序晚于原有样式，可直接覆盖。

   三十一、窄屏下的"消息"面板（客户中心）
   --------------------------------------------------------------------------
   问题：.notify-panel 是 `position:absolute; right:0; width:320px`，
   以 .notify-wrap（"消息"按钮，只有约 75px 宽）为定位基准。
   窄屏时 right:0 会让面板左边缘跑到屏幕之外
   （实测 382px 视口：面板 rect.x = -231，只剩右侧一条可见）✗

   注意：本项目的移动端规则里有 `body.dark-app > .topbar { position: static !important }`
   （第 1998 行，移动端顶栏不固定），所以**顶栏不能作为定位基准** ✗
   （否则面板会以"初始包含块"定位，top:100%+8 直接落到可视区下方 ✗）。

   修法：把定位基准换成"顶栏里那一整组"（实测 x:14 / 宽:354，横排竖排都成立），
   面板左右各留 12px、组下方 8px，宽度自适应。

   三十二、手机端体检发现的 6 处配色问题（含两处"几乎看不见"）
   --------------------------------------------------------------------------
   病因（第 1 条）：登录/注册页的卡片类名是 .auth-card（深色模式下第 319 行有深色卡片规则），
   而找回密码/重置密码用的是 .card ✗ 没被覆盖 → 深色模式下仍是白卡片，
   但第 323 行的 `html[data-theme="dark"] .auth-page label{color:#eaf3ff}` 照样生效
   → 白底浅字，实测对比度只有 1.12 ✗✗（同页的 .tip / .back / .msg 同因）
   修法：把 .card 与 .auth-card 同等对待（深色卡片），标签/说明/链接的颜色随之恢复可读。
