@hipp0 再次感谢您提出这个问题！我们推送了一个更新，使 site_name 变量在所有三个标题字段上都可用：

Right now site_name is only available on the welcome-banner header field for ano…nymous visitors. This makes it available for all members. ### Before `site_name` is only available for anonymous visitors: <img width="380" height="450" alt="image" src="https://github.com/user-attachments/assets/4f973b49-f1f1-4355-8ea1-f7b43ff0914a" /> Using it in other fields results in a validation error: <img width="690" height="288" alt="image" src="https://github.com/user-attachments/assets/336139c4-100f-44e9-95d4-98494dd0aaf2" /> ### After `site_name` is available on all header fields: <img width="365" height="495" alt="image" src="https://github.com/user-attachments/assets/2654734e-10fa-4078-8c9c-88adf96bb870" />
