//! Advanced integer-coordinate curve API.
//!
//! Integer paths and shapes are plain structural containers. [`IntCurveOverlay`]
//! validates that inputs are non-empty and closed and that rational arcs meet
//! the integer kernel invariants when they are added. Most applications should
//! prefer the crate-level float API, which selects and applies an integer
//! conversion scale automatically.
//!
//! Every integer geometry type uses the sealed [`CurveInt`] engine bound. The
//! supported coordinate types are `i16`, `i32`, and `i64`.
