Compose Multiplatform Patterns

If you're building Compose UI across Android, iOS, desktop, or web, this covers the patterns you'll actually use: single state objects with StateFlow, type-safe navigation with serializable routes, slot-based composable design, and platform-specific UI with expect/actual. The event sink pattern is smart for screens with lots of user actions, and the performance section gets specific about stable types, derivedStateOf, and lazy list keys. It's opinionated aboutViewModel + StateFlow over raw mutableStateOf and warns against passing NavController down the tree. Most useful when you're past hello world and need to structure a real KMP app with shared UI that doesn't fight the framework.
