+//! Service trait definitions — use-case interfaces for session management
+//! and OAuth flows.
+//!
+//! These traits define the boundary between the application orchestration
+//! layer and the domain. Implementations live in the application layer.
+//!
+//! # Traits
+//!
+//! - [`SessionService`] — create, list, archive sessions
+//! - [`OAuthService`] — start PKCE flow, complete code exchange, retrieve token
