//! Concrete Riemannian manifold implementations.
//!
//! Each submodule provides one manifold family (its embedding, projection,
//! exponential/logarithm maps, distance, and curvature). The core trait and
//! the [`ManifoldSpec`](crate::manifold::ManifoldSpec) builder live one level
//! up in [`crate::manifold`]; these are the structs it instantiates.
//!
//! Primary manifold types are re-exported at the crate root so callers use one
//! canonical import surface.
