//! Pure geometry engine for spatial split management in ratatui applications.
//!
//! This crate provides a `SplitManager` that manages a binary tree of horizontal
//! and vertical splits, computing pixel-accurate areas for each leaf. It handles
//! spatial navigation (beam/raycasting), tree mutations (split, close, resize),
//! and area caching with automatic invalidation.
