## Overview

Rick-n-Morty is an Android character browser: users view the first page of characters, select one, and see biographical details and episode information. The graph follows the documented list/detail workflow and the sampled repository and detail-screen implementation. Main-screen and ViewModel wiring is inferred from the named modules and documented behavior; unsampled internal calls are not expanded beyond that evidence.

Main entry points: [`app/src/main/java/com/nauhalf/ricknmorty/view/detail/DetailActivity.kt`](https://github.com/nauhalf/rick-n-morty/blob/master/app/src/main/java/com/nauhalf/ricknmorty/view/detail/DetailActivity.kt) (Character detail), [`app/src/main/java/com/nauhalf/ricknmorty/view/main/MainActivity.kt`](https://github.com/nauhalf/rick-n-morty/blob/master/app/src/main/java/com/nauhalf/ricknmorty/view/main/MainActivity.kt) (Character list), [`app/src/main/java/com/nauhalf/ricknmorty/data/character/implementation/repository/CharacterRepositoryImpl.kt`](https://github.com/nauhalf/rick-n-morty/blob/master/app/src/main/java/com/nauhalf/ricknmorty/data/character/implementation/repository/CharacterRepositoryImpl.kt) (Character repository), [`app/src/main/java/com/nauhalf/ricknmorty/view/detail/DetailViewModel.kt`](https://github.com/nauhalf/rick-n-morty/blob/master/app/src/main/java/com/nauhalf/ricknmorty/view/detail/DetailViewModel.kt) (Detail ViewModel)
