//! Hexagonal grid support for pointy-top axial coordinates.
//!
//! This module provides hex-grid counterparts of the square-grid types
//! in the parent crate: 6-connected graph construction, BFS traversal,
//! smoothness analysis, D6 alignment transforms, and rectification.
//!
//! # Coordinate Convention
//!
//! Axial coordinates `(q, r)` are stored in [`GridIndex`](crate::GridIndex)
//! where `i = q` and `j = r`. Pointy-top orientation: `q` increases eastward,
//! `r` increases south-eastward.
