/* ==========================================================================
   管理后台 · 液态玻璃设计系统（console-glass.css）
   --------------------------------------------------------------------------
   灵感来源：Apple 液态玻璃（Liquid Glass, WWDC25）——半透明 + 背景模糊 +
   高饱和度还原 + 边缘镜面高光 + 内阴影模拟厚度 + 背后可折射的色彩斑块。
   落地要点（业界通用做法）：
     ① backdrop-filter: blur() saturate() 让背后内容失焦并显色
     ② 低 alpha 背景，避免"灰蒙蒙"的毛玻璃感
     ③ ::before + mask-composite 做渐变描边（顶部亮、底部暗的镜面反射）
     ④ inset box-shadow 模拟玻璃厚度与边缘暗角
     ⑤ 性能取舍：只有「大容器」做真实 backdrop-filter，小卡片用半透明+内阴影
        代替，避免几十个模糊层把帧率拖垮
   仅 console.html 引用，不影响前台页面。

/* ============================
   Toast 公告面板（2026-10-23 布局优化）
   ------------------------------------------------------------
   ① 编辑器改两列网格：标题/内容/保存条占满整行，类型与投放网页并排，
      停留时长与生效时间窗用三列子网格 —— 原本单列纵向排列导致面板过长。
   ② 列表卡片改为「类型图标 | 主体 | 操作」三段式：标题与状态徽章一行、
      摘要单行省略；操作按钮固定在右侧不换行。
      ⚠ 早前复用 .motion-fx-card（flex 三列 + align-items:center）时，
      长文本会把按钮组挤到与文字重叠，出现「敬请用!」挤成一团的错位。
