//! Two-dimensional Euclidean geometry (ℝ²).
//!
//! This module provides basic types for working in the Euclidean plane:
//!
//! - [`Point`] — a 2D point (or vector) with `x` and `y` components,
//!   supporting arithmetic, dot product, and cross product.
//! - [`Rect`] — a closed axis-aligned rectangle, stored as a pair of
//!   [`r1::Interval`](crate::r1::Interval)s.
//!
//! These types are primarily used internally to represent cell bounds in
//! `(u, v)` cube-space coordinates during S2 cell operations.
