-## v1.3.9
-重新实现分页测量，清理多余日志。
-- 重新实现分页测量：构建隐藏的“测量页面”，与真实页面同样的宽度、内边距（40px）和 class，逐个把克隆元素追加进去，利用 scrollHeight 决定是否换页，保证 margin 折叠后计算准确 (src/xiaohongshu/paginator.ts:57；waitForLayout 新增)。
-- 当元素放不下当前页时，移除测量克隆并把已排内容写入分页，再以该元素开启新页；不可分割元素允许独占一页即便超高 (src/xiaohongshu/paginator.ts:101)。
-- 清理多余日志，同时共用 PAGE_PADDING 常量让 renderPage 和测量逻辑保持一致 (src/xiaohongshu/paginator.ts:182)。
