 * 官网动效：抽屉 / 滚动播放 / 滚动揭示 / 阅读进度 / 悬浮反馈
 *
 * 改这个文件前先读三条硬规矩：
 * 1) 只有 html 上带 .xmo-on（JS 正常启动后才加）才会把元素先藏起来 ——
 *    JS 没跑起来时内容照常显示，绝不能出现「页面源码里有字但用户看不见」。
 * 2) 颜色只用官网三色：#1467A8 品牌蓝、#EAF4FB 浅蓝、#6B7280 灰、#FFFFFF 白，
 *    不引入第四种色相。
 * 3) 系统的「减少动态效果」偏好优先；编辑模式下 JS 会直接退出，不干扰拖拽编辑。
 *
 * 资源不走 assets bundle（静态直引），避免触发前端样式包重编译。
