description: Extract a composable from amethyst to shared code

Extract the component `$ARGUMENTS` from the Android app to shared KMP code:

Process

1. **Locate the component** in the amethyst module:

   find amethyst/src -name "*$ARGUMENTS*"
   grep -r "fun $ARGUMENTS\|class $ARGUMENTS" amethyst/src/

2. **Analyze dependencies**:

Android-specific imports (Context, Intent, etc.)
Platform APIs (Camera, MediaStore, etc.)
Android Compose specifics vs standard Compose

3. **Identify what can be shared**:

Pure Composable functions → `commons/commonMain/`
Business logic → `quartz/commonMain/`
Platform-specific → create expect/actual

4. **Create shared version**:

Move to appropriate shared module
Replace Android imports with multiplatform alternatives
Add expect declarations for platform-specific parts

5. **Update references**:

Change imports in amethyst module
Add implementations in desktopApp if needed

Common Replacements

| Android | Multiplatform | |---------|---------------| | `LocalContext.current` | expect/actual or parameter | | `stringResource()` | `Res.string.*` | | `painterResource()` | `painterResource(Res.drawable.*)` | | `Toast.makeText()` | Custom snackbar/notification | | `Intent` | expect/actual for navigation |
