研究方向

The issue requests adding a visual indicator when the app is served from an offline cache. Investigate the existing service worker implementation in the repository. Look for service worker registration and cache strategies. The frontend likely uses JavaScript; identify where to add a UI element (e.g., a banner) to show offline status. Review any existing comments for additional requirements. Implement using the service worker's 'fetch' event to detect offline mode.
