/* share-dock.css
 *
 * 移动端底部固定分享条（"Mobile Share Dock"）。
 * 用法：在工具/模板/场景详情页通过 commonSections :: mobileShareDock 注入。
 * 设计原则：
 *   - 仅在窄屏（≤ 768px）显示，PC 端隐藏（PC 端用现有的 .tool-share-bar 行内组件）
 *   - 底部固定，给底部 tabbar 让 50px 空间（结合 mobile-tabbar.css 总高度 ≈ 116px）
 *   - 半透明毛玻璃 + 圆角顶边，避免与页面内容割裂
 *   - 4 按钮等宽：💬 分享 / 📷 长图 / 🔗 二维码 / 📋 复制
 *   - 隐藏在 admin 后台、首页等不需要分享的页面（由 JS 判断后加 body[data-share-dock="off"]）
