//! # brepkit-check
//!
//! Topology algorithms for brepkit B-Rep models.
//!
//! This is layer L2, depending on `brepkit-math`, `brepkit-topology`,
//! and `brepkit-geometry`.
//!
//! Four subsystems:
//! - **classify** — point-in-solid classification (ray casting + winding numbers)
//! - **validate** — hierarchical shape validation (geometric + topological checks)
//! - **properties** — geometric properties (volume, area, CoM, inertia tensor)
//! - **distance** — minimum distance and extrema between shapes
