Android / KMP Module Structure

Core Philosophy

• Feature-layered modularization: split by feature first, then by layer within each feature.
• Clean Architecture layers: presentation → domain ← data. Domain is innermost and depends on nothing.
• Code lives in a feature module unless it is needed by more than one feature — then it moves to the appropriate core submodule.
• Features never depend on each other. Cross-feature shared data belongs in core:domain (domain models) or core:presentation (shared composables/UI logic), not in the owning feature.
