//! Sketches: points and curves on a plane, geometric constraints and driving dimensions, a
//! Levenberg–Marquardt constraint solver with degree-of-freedom analysis, and closed-profile
//! (region) detection for features.
//!
//! The solver is our own clean-room implementation (residual functions per constraint, local
//! finite-difference Jacobians, damped Gauss–Newton per connected component, rank analysis by
//! Gaussian elimination). See `plan/architecture.md` §sketch.
