#Project Structure Rules

#Single Module

• This is a single-module Android project — all code lives under :app
• Do not create new Gradle modules or suggest modularization

#Dependency Injection

• Manual DI via AppContainer interface + DefaultAppContainer implementation
• Do not introduce Hilt, Dagger, Koin, or any DI framework
• New repositories/services are added to AppContainer and lazily initialized in DefaultAppContainer
• Access the container via (application as VBHelper).container

#External Libraries

• vb-nfc-reader is resolved from mavenLocal() — it must be installed locally before building
• Version catalog is in gradle/libs.versions.toml — all dependency versions go there
• New dependencies must be added to the version catalog first, then referenced via libs.* accessor

#Package Conventions

• New screens: create a sub-package under screens/ (e.g., screens/myFeature/)
• Each screen package contains: MyFeatureController.kt (interface), MyFeatureControllerImpl.kt, MyFeatureScreen.kt
• Shared UI components go in components/
• Domain models go in domain/ organized by feature sub-package
