- * Promo view on the recent tabs page that encourages the user to sign in to Chrome or enable sync.
- * This view handles three scenarios:
- *
- * 1. The user is not signed in: Shows the sign-in screen from first run.
- * 2. The user is signed in but sync is disabled: Displays a message encouraging the user
- *    to enable sync with a corresponding button.
- * 3. The user is signed in and sync is enabled: Displays a message instructing
- *    the user to sign in and open tabs on another device to use this awesome feature.
