36 * Setup Wizard's version of EncryptionInterstitial screen. It inherits the logic and basic
37 * structure from EncryptionInterstitial class, and should remain similar to that behaviorally. This
38 * class should only overload base methods for minor theme and behavior differences specific to
39 * Setup Wizard. Other changes should be done to EncryptionInterstitial class instead and let this
40 * class inherit those changes.
