//! Generic 2D projective grid graph construction, traversal, and homography tools.
//!
//! This crate provides reusable algorithms for building 4-connected grid graphs
//! from detected 2D corners, assigning grid coordinates via BFS traversal,
//! and computing projective mappings (homographies) for grid rectification.
//!
//! It is pattern-agnostic: the [`NeighborValidator`] trait lets callers plug in
//! pattern-specific logic (chessboard orientation checks, marker constraints, etc.)
//! while the graph construction, traversal, and geometry remain generic.
//!
//! # Hex Grid Support
//!
//! The [`hex`] module provides 6-connected hexagonal grid counterparts for
//! pointy-top axial coordinates `(q, r)`.
