//! 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.
//!
//! Before iterating, a constructive seed places every point that two loci on already placed
//! points pin down (circles, rows and columns, lines through placed points, offsets from
//! placed lines, tangency, midpoints, mirrored points, coincidence), on the branch that keeps
//! the orientation the point had before the solve, so dimension edits do not fold the sketch
//! into a mirrored solution or flip an arc out of its corner. The seed only moves the starting
//! point: the iteration still verifies every constraint and the rank analysis still decides
//! the degrees of freedom.
