//! Canonical style resolution interfaces for the Citum citation engine.
//!
//! This crate provides a lightweight bridge between the schema layer
//! (which defines style models) and the store layer (which implements
//! persistence and network resolution). It minimizes dependencies
//! to facilitate integration by third-party tool authors who don't
//! need the full store logic.

/// Error types and conversion helpers.

/// schema models and resolution logic.
