+## Architecture
+
+This is a **Kotlin Android application** using Jetpack Compose and Material 3.
+
+### Module Structure
+
+- **`:app`** - Main Android application entry point
+- **`:core:ui`** - Shared design system library with theming components
+- **`:feature:orb`** - Orb feature with Compose UI and WebGPU rendering
+
+### Dependency Injection (Koin)
+
+Uses Koin 4.1.1 for dependency injection. Modules are defined in `app/src/main/java/io/visus/orbis/di/AppModule.kt`.
+
+```kotlin
+// Define dependencies using autowire DSL (constructor params resolved automatically)
+val appModule = module {
+    singleOf(::MyRepository)          // Singleton
+    factoryOf(::MyUseCase)            // New instance each time
+    viewModelOf(::MyViewModel)        // ViewModel scoped to lifecycle
+}
+
+// Inject in Android classes via delegate
+class MyActivity : ComponentActivity() {
+    private val viewModel: MyViewModel by viewModel()
+}
+```
+
+### Design System (core/ui)
+
+The `core/ui` module provides a custom theme system (`OrbisTheme`) with:
+
+- **Color.kt** - Color palette with light/dark mode support (grayscale, red, blue, green schemes with 10 variants each)
+- **Typography.kt** - 12 text styles (h1-h4, body1-3, label1-3, button, input)
+- **Theme.kt** - Composable theme wrapper that provides colors and typography via CompositionLocal
+- **foundation/** - Elevation animations and custom ripple effects
+
+### Theme Usage
+
+```kotlin
+OrbisTheme {
+    // Access theme values via:
+    OrbisTheme.colors.primary
+    OrbisTheme.typography.h1
+}
+```
+
+## Key Configuration
