//! `multicalc` — single- and multi-variable calculus for `no_std` Rust: derivatives,
//! integrals, Jacobians and Hessians, vector-field operators, and Taylor approximation.
//!
//! All math is on `f64`, with transcendentals from [`libm`] so it works without `std`.
//! Fallible operations return [`utils::error_codes::CalcError`].
