LITE previews every look and feature but export/render is blocked while a PRO look is in use, and every LITE export carries the RECIPESCAM mark. Keys are generated offline (FNV-1a checksum over a fixed secret, 16 chars from a no-ambiguity alphabet) and activate one machine or a thousand: nothing is bound to a device, so revoking a leaked key needs Play Billing plus server validation. CREATE, FAVORITED, the star chip and the TopBar + SAVE now answer with a PRO prompt instead of a silent no-op; CREATE still drafts and applies the look so LITE can try it, it just cannot persist. The SETTINGS card also lifts above the keyboard now: RN Modal is its own dialog window, so the IME never resizes or pans it and the UNLOCK row was sitting under the keys.
