/* ============================================================
 * 房飞布 · 分享弹框（底部抽屉）  share-sheet.css
 *
 * 为什么独立成文件：
 *   这些样式原先内联在 Widget/Nav/foot3.html 里。CSS 的 @keyframes 会写成
 *   `from{...} to{...}`，而 ThinkPHP 模板引擎把 `{内容}` 当作模板标签解析，
 *   直接编译成 <?php echo ...?>，导致「syntax error, unexpected ':'」整页 500。
 *   样式放进 .css 文件由浏览器直接加载，不经过模板引擎，彻底避免这类冲突。
 *
 * 作用范围：.share_user 悬浮按钮 + .share_mask 遮罩 + .share_box 面板
 * 使用页面：引用 Widget/Nav/foot3 的 6 个页面
 *   Index/index、Index/service、Index/searchResult、Index/viewWT、
 *   Index/wtDetail、Gservice/detail
