/* ===== 校验反馈：固定定位 Toast（不受弹窗滚动位置影响，永远可见） =====
   背景 1：弹窗表单很长，真正的滚动容器是 .modal（max-height:92vh + overflow-y:auto），
        而 #nameCheckError 位于表单顶部。用户滚到底部点提交 → 校验失败 →
        错误提示被渲染在视口上方数百像素处 → 完全看不到 → 表现为「点按钮没反应」。
   背景 2（2026-10-02）：本文件曾长期没有版本号，浏览器缓存到旧版时以下规则缺失，
        提示元素退化成 body 末尾的普通块级元素、被弹窗遮罩完全盖住 → 症状与背景 1 相同。
        ⇒ 因此 main.js 里 **所有提示样式一律内联写死**，这里的规则仅作补充/一致性用途，
          即使本文件是旧缓存也**不会**影响提示可见性。改样式时请同步 main.js 的 WB_TOAST_* 常量。 */
