//! # brepkit-operations
//!
//! CAD modeling operations for B-Rep solids. Layer L3, depending on
//! `brepkit-math`, `brepkit-topology`, `brepkit-geometry`, `brepkit-algo`,
//! `brepkit-blend`, `brepkit-heal`, `brepkit-check`, and `brepkit-offset`.
//!
//! # Module families
//!
//! | Family | Modules | Purpose |
//! |--------|---------|---------|
//! | **Core** | [`primitives`], [`extrude`], [`revolve`], [`sweep`], [`loft`], [`pipe`], [`helix`] | Shape creation |
//! | **Transform** | [`transform`], [`copy`], [`mirror`], [`pattern`] | Spatial operations |
//! | **Boolean** | [`boolean`], [`mesh_boolean`] | Set operations |
//! | **Blend** | [`fillet`], [`chamfer`], [`blend_ops`] | Edge smoothing |
//! | **Offset** | [`offset_face`], [`offset_trim`], [`offset_v2`], [`offset_wire`] | Wall thickness |
//! | **Surface** | [`fill_face`], [`thicken`], [`shell_op`], [`draft`], [`section`], [`split`] | Surface/solid modification |
//! | **Repair** | [`heal`], [`defeature`], [`sew`], [`untrim`] | Shape fixing |
//! | **Analysis** | [`measure`], [`distance`], [`classify`], [`validate`], [`query`], [`feature_recognition`] | Interrogation |
//! | **Tessellation** | [`tessellate`] | Mesh generation |
//! | **Infrastructure** | [`assembly`], [`compound_ops`], [`evolution`], [`sketch`] | Utilities |
