//! Error types layered by responsibility.
//!
//! - [`DomainError`] — pure domain failures (invalid entity construction,
//!   constraint violations, unresolved references). Step C carry: every
//!   `domain::entity::*` constructor returns `Result<_, DomainError>`.
//! - [`WireError`] — top-level facade that wraps `DomainError` via `From`
//!   plus residual infrastructure / catch-all variants (`Storage` / `Other`).
//!   Application + Infrastructure layers may surface either layer's error.
//!
//! Future split (Application / Infrastructure dedicated enums) is carry —
//! current scope keeps `Storage` / `Other` flat under `WireError`.
