Sign in with Devtune

Signing in links PicoBuild to your Devtune account so it can issue and refresh your license.

From Settings → Account, choose "Sign in with Devtune" — the app opens this website in your browser, you approve the connection on the "Connect PicoBuild" page, and the browser hands a one-time code back to the app over a local loopback address (127.0.0.1). Nothing is copied and pasted.

Once connected, the app registers this device and downloads a signed license token. You stay signed in across restarts; sign out from Settings → Account to release the device seat.
