//! Build script for `polyplug_python`.
//!
//! Emits the linked CPython library name (e.g. `python3.14`) as the
//! `POLYPLUG_PYTHON_LIB_NAME` compile-time environment variable so the loader
//! can promote libpython's symbols into the global namespace at runtime when
//! the loader cdylib is `dlopen`ed by a non-Python host (see `context.rs`).
