//! Square (4-connected) grid support.
//!
//! Mirrors the [`hex`](crate::hex) module for square grids. Modules parallel
//! the hex submodules:
//!
//! | Module | Responsibility |
//! |---|---|
//! | [`direction`] | 4 cardinal directions + neighbor delta helpers |
//! | [`alignment`] | D4 rotations and reflections on `(i, j)` |
//! | [`index`] | `(i, j)` cell identifier shared with the hex side (axial `(q, r)`) |
//! | [`mesh`] | Per-cell homography mesh over a regular grid |
//! | [`rectify`] | Global homography from grid corner positions |
//! | [`smoothness`] | Midpoint prediction and outlier detection |
//! | [`validators`] | Ready-to-use [`NeighborValidator`](crate::NeighborValidator) implementations |
//!
//! Top-level types are re-exported at the crate root for back-compat.
