Status, without invented numbers.运行状态，不编数字。

This page does not read a live status feed and does not publish uptime. The classroom login, join codes, and sync are the existing product. The pages in this preview are demos until the owner says to ship them.这一页不读取实时状态，也不公布可用率。课堂登录、课堂码和同步是已经有的产品。这次预览里的页面在所有者说发布之前，都是演示。
