+//! K-Notes Domain Layer
+//!
+//! This crate contains pure domain logic with no I/O dependencies.
+//! It follows hexagonal architecture principles where:
+//!
+//! - **Entities**: Core business objects (Note, Tag, User)
+//! - **Errors**: Domain-specific error types
+//! - **Repositories**: Port traits defining data access interfaces
+//! - **Services**: Use cases orchestrating business logic
