//! Geometric primitives and queries for rustsim.
//!
//! This crate is intentionally tiny and dependency-free. It provides:
//!
//! - [`Vec2`] and [`Vec3`] type aliases over `[f64; 2]` and `[f64; 3]` with
//!   free-function arithmetic in the [`vec2`] and [`vec3`] modules.
//! - Axis-aligned bounding boxes [`Aabb2`], [`Aabb3`].
//! - Segments [`Segment2`], [`Segment3`] with closest-point queries.
//! - Rays [`Ray3`] and planes [`Plane3`] with ray-plane intersection.
//! - Triangles [`Triangle3`] with closest-point and ray-triangle
//!   intersection (Möller–Trumbore).
//! - Spheres [`Sphere3`] with sphere-vs-AABB / sphere-vs-triangle tests.
//!
//! All functions are `f64`. No `unsafe`. No external crates. No allocation
//! in hot paths.
