//! Ordinary differential equation integrators.
//!
//! - [`Rk4`] — fixed-step classic Runge–Kutta.
//! - [`Rk45`] — adaptive Dormand–Prince 5(4) with PI step control and cubic-Hermite dense output.
//!
//! Both are generic over the state `Vector<N, T>` and any [`Numeric`](crate::Numeric) scalar, so the
//! same integrator runs at `f32`/`f64` or through an autodiff scalar.
