我的个性签名是#include<bits/stdc++.h>。

但是我用 https://luogu-card.vercel.app/about?id=356003生成卡片挂在主页上，发现无法显示。用浏览器访问这个网页，看到

This page contains the following errors:

error on line 33 at column 390: error parsing attribute name
Below is a rendering of the page up to the first error.

然后生成的图里个性签名没了……

请问这是怎么回事？
