State in Jetpack Compose
summary
Builds a small wellness app in Jetpack Compose: a water counter and a LazyColumn of ~30 wellness tasks that can be checked or removed. Uses mutableStateOf with remember (and switches to rememberSaveable to survive rotation), demonstrates state hoisting and unidirectional data flow, and makes the task list observable with toMutableStateList. Shows ViewModel migration so list mutations survive configuration changes. UI updates after button clicks and deletes, Layout Inspector confirms recomposition behavior.
