//! Domain-agnostic Keplerian dynamics on typed quantities.
//!
//! ## Scientific scope
//! This crate provides reusable two-body astrodynamics primitives: anomaly
//! solving, Keplerian elements, Lambert transfers, and transfer invariants.
//!
//! ## Technical scope
//! Public APIs depend only on `qtty` and `affn`; no time-scale or astronomy
//! orchestration types are introduced here.
//!
//! ## References

//!   Astrodynamics*.
