//! Exact scalar arithmetic tower.
//!
//! The scalar types form a tower of increasing generality:
//!
//! - [`Rat`] — rational numbers (i128/u128), the fast path
//! - `BigRat` — arbitrary-precision rationals (automatic on i128 overflow)
//! - [`RadicalElement`] — element of a radical extension tower ℚ(α₁,...,αₖ)
//!
//! [`Scalar`] wraps all three and promotes/demotes automatically.
//! Every `Scalar` implements `Eq` and `Ord`.
