修改前端文件后重新部署，显示的还是老的页面

This issue has no description.

The issue has no body, file names, entry points, test references, reproduction steps, or expected result beyond an old page appearing after frontend changes and redeployment. Start by reproducing the deployment behavior and tracing which frontend artifact is served; done means the changed page is served after redeployment and the result is covered by a repeatable verification.
