//! `integral-codegen` — pure-Rust build-time generation (see `ARCHITECTURE.md`).
//!
//! Invoked from `build.rs` scripts to emit specialized per-angular-momentum
//! kernels and coefficient tables (e.g. Boys Chebyshev tables) as plain Rust
//! source — keeping all build-time code generation in one language rather than a
//! separate external generator toolchain.
//!
//! Currently a stub; the first real generator (Boys interpolation tables) will
//! land when the const-generic kernel path is optimized.

#![forbid(unsafe_code)]

/// Placeholder generator entry point, exercised by a unit test so the crate is
/// wired into the build from the start.
