3//! - [`os`] — the one-electron Obara–Saika engine (overlap, kinetic,
4//! nuclear-attraction, and multipole/dipole integrals).
5//! - [`os_eri`] — the OS/HGP two-electron (ERI) engine.
6//! - [`rys`] — the Rys-quadrature ERI engine.
7//! - [`operator`] — the L2 one-electron operator DSL over `r` and `p`.
8//! - [`deriv`] — geometric (nuclear-coordinate) first derivatives.
