//! PyO3 shims for `crate::presets` (Layer-1) — the precompiled-pipeline presets.
//!
//! Each shim is a thin wrapper over a Layer-1 preset core. The cores compose
//! other modules' transforms and live in `src/presets.rs` (pyo3-free,
//! `pub(crate)`); these shims validate at the boundary and convert the native
//! `ErrorRepr` to a Python exception via `?`. See #38.
