A sketch text gets an optional style: bold and italic faces (a slanted fallback for italic), left/center/right alignment, letter and line spacing, and a path curve of the same sketch for the baseline to follow (reverse takes the other side). Edit Text gets B/I toggles, alignment, spacing fields and a Path chip, all live. The style is saved only when not plain and is noted under format 18.

//! 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.
