There is no "retry" or "redeploy" button in the Railway dashboard for failed builds. When a deployment fails (even from transient errors), the only ways to retry are:

1. Push an empty commit (pollutes git history)
2. Use the Railway CLI

Neither is acceptable for production. Need a simple "Retry" button on failed deployment cards in the dashboard.

You can redeploy the old successful deployments, but they are just deploying from the old git commit. I won't redeploy from the head.
