When port 3000 is unavailable, Nuxt/Vite automatically picks an alternative port: ``` [get-port] Unable to find an available port (tried 3000 on host "localhost"). Using alternative port 3001. ``` But the connector CORS config was hardcoded to only allow the prod host and `http://localhost:3000`, causing local authentication to fail in an opaque manner. It now uses a regex pattern to allow any localhost port. This seems fine from a security perspective, and there aren't alternatives with great DX that I can think of.
