//! Automatic differentiation primitives for OxiProj.
//!
//! This module provides forward-mode dual numbers enabling exact Jacobian
//! computation for projection functions, Tissot indicatrix, and uncertainty
//! propagation — all without any external AD crates.
//!
//! # Modules
//!
//! - [`dual1`]: First-order forward-mode dual number (`Dual1<N>`).
//! - [`dual2`]: Second-order forward-mode dual number (`Dual2<N>`).
