1//! Hexagonal grid support for pointy-top axial coordinates.
2//!
3//! This module provides hex-grid counterparts of the square-grid types
4//! in the parent crate: 6-connected graph construction, BFS traversal,
5//! smoothness analysis, D6 alignment transforms, and rectification.
6//!
7//! # Coordinate Convention
8//!
9//! Axial coordinates `(q, r)` are stored in [`GridIndex`](crate::GridIndex)
10//! where `i = q` and `j = r`. Pointy-top orientation: `q` increases eastward,
11//! `r` increases south-eastward.
