#Compose UI Conventions

#Screen Structure

• Screen composables receive NavController + a Controller interface (not impl)
• Controller interfaces define callbacks and state flows for the screen
• Do not use ViewModel — this project uses Controller pattern instead
• Controllers use callback lambdas passed to composables, not StateFlow for events

#Material 3

• Use Material 3 components (androidx.compose.material3.*)
• Support dynamic color (Monet) on Android 12+ — avoid hardcoded colors
• Use MaterialTheme.colorScheme and MaterialTheme.typography tokens

#State Management

• Collect Flows as Compose state via collectAsState() or collectAsStateWithLifecycle()
• Keep UI state in the Controller, not in the composable (except transient UI state like scroll position)
• Composable functions should be stateless where possible — receive data and callbacks as parameters
