Build me the app for our capstone project in Kotlin for Android. I want a clean, polished mobile app with a simple modern interface that feels finished, not like a demo. Since there is no README yet, please make reasonable choices for the structure and basic user flow, and set up the project so it is easy to keep building on later.

Make sure the app opens properly, has a clear home screen, and includes a few useful screens or sections that make sense together. Keep the code organized and easy to follow, and use sensible defaults for styling and navigation. If you need to check current Android or Kotlin docs online to make sure the setup is modern, go ahead. Also make sure the project builds cleanly in Android Studio and does not have any obvious broken pieces.
