Sample: categories are paths, not subdomains示例：分类是路径，不是子域名
A stub so the site has a second category. The FinOps essay is the real article on windtask.com.一个占位页，用来让站点有第二个分类。Windtask 上真正的文章是那篇 FinOps 随笔。
Notes笔记
Short site notes. This shelf exists so a second category has a real route.站点短记。这个分类用来保证第二个分类有一条真实路径。
