//! VectorCraft path operations: booleans (Pathfinder), shape builder regions, offset, outline stroke,
//! simplify and the other Object → Path commands.
//!
//! Booleans are curve-preserving: `linesweeper`'s robust sweep-line works directly on cubic
//! Béziers, and the pieces it splits curves into are refitted afterwards so results carry few
//! anchors. See the crate README for the API overview.
