//! Inverse kinematics (IK) solvers for serial robot arms.
//!
//! This module provides two complementary approaches to solving the inverse
//! kinematics problem (finding joint angles that realise a desired
//! end-effector pose):
//!
//! - **Geometric / closed-form** ([`geometric_6dof`]): Pieper solution for
//! standard 6R manipulators with a spherical wrist. Returns up to 8
//! candidate solutions analytically with no iteration.
//!
//! - **Numerical** ([`numerical_ik()`]): Levenberg-Marquardt / damped
//! least-squares iteration for arbitrary N-DOF robots. Handles joint
//! limits via null-space projection.
