Get broken app previews back on screen.
Diagnoses broken or missing app previews and helps restore their services, tabs, and asset loading.
When to use it
Use when a preview tab is broken or missing, assets return 404 errors, or running services need to be listed.
Give it a preview problem; it diagnoses the service, asks which saved project to restart when needed, and explains how to reopen the preview.
What you provide
The workflow depends on the frontend's iframe-based Preview panel and its reverse-proxy preview URLs.
