<<<END>>>

等等——我不该输出 `</style>` 或 `<<<END>>>`。标记只能是 `` 和 ``。让我把末尾那段去掉。

另外，在 880px 的媒体查询里，`.contact-links__list li:nth-child(1)` 那条规则是多余的——去掉。还有网格变成两列之后，边框样式也还好。

让我清理一下，把最终输出重新发一遍。

还有 `.page-contact .filter-chip` —— 共享样式已经有了。没问题。

还有一处：`.page-contact .flow__step:nth-child(2)` —— `.flow` 是 `<ol>`，`li` 都是子元素，可以正常生效。

另外 `counter-reset: none;` 这个可以删掉。

好，就这样定稿吧。
