1. 首页大面积空白：useScrollReveal 添加 MutationObserver， 确保异步子组件的 .reveal 元素也能触发入场动画 2. 小红书/游记封面图不显示： - 小红书 CDN 签名链接过期+防盗链，全部下载到本地 - 新增 download-covers.mjs 脚本批量下载封面 - 新增 useImageProxy composable 转换外部 URL - 页面 img 标签添加 referrerpolicy="no-referrer" - 管理端保存时自动下载外部封面图到本地 - 种子数据更新为本地路径 3. 定制页微信号文字替换为二维码图片 4. prerender 路由添加 /xiaohongshu 和 /youji Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
