hewad-mubariz/reactnative-50-days — reverse-engineered prompt

Build me a React Native showcase app based on this 50 days UI challenge idea. I want a simple mobile app where I can open a home screen, see all the mini demos, and tap into each one to preview the interaction and animation.

Please include the kinds of pieces shown here, like bouncy and circular onboarding, dynamic tabs, sticky header, animated cards, swipeable rows, loaders, shapes, dial and floating buttons, audio waveform recording UI, flip cards, expandable lists, card deck, rating animations, gauges, progress views, charts, timers, search, and other playful motion experiments from the folders in this repo. It does not need to feel like a production app, more like a polished demo gallery for inspiration.

Make the navigation and layout clean, keep each demo isolated on its own screen, and add a nice landing page so it is easy to browse everything. If anything is unclear, look up current docs online and fill in the gaps in a sensible way.
