Clean Authenticator Onboarding UI Mockups

Using REFERENCE_0 and REFERENCE_1 as design references, recreate the same four mobile onboarding screens as a clean, high-fidelity UI mockup, rather than a photograph of a laptop screen. Remove all perspective distortion, laptop/browser backgrounds, reflections, and camera artifacts. Place the four iPhone-style screens face up, evenly distributed across a light gray canvas, arranged in a row. Retain the dark mode version from REFERENCE_0, along with the same screen order, typographic hierarchy, blue security visual style, rounded phone borders, status bar, skip links, bottom home indicator, and CTA structure. Strictly retain the following four screens: 1) an authenticator account protection page with "Get Started," 2) a timely reminder page with a notification toggle and "Continue," 3) an end-to-end encryption page with a shield/lock icon, social icons, and "Continue," and 4) a Face ID quick setup page with a scan overlay, toggle, and "Continue." Ensure the UI is clear, refined, meets app store display standards, with sharp, legible text and consistent spacing.
