Create a realistic, photorealistic-quality mobile app interface mockup. Design a clean, modern smartphone screen with a polished UI: top status bar, app navigation, hero card or feature header, scrollable content sections, and a bottom tab bar. Use balanced typography, clear visual hierarchy, soft shadows, rounded corners, and a tasteful color palette. The output should feel like an actual production app screen captured from a real device, with composition and aesthetics ready to be used as a portfolio or design-review reference.
