"""Offline sanity check for the contextvm_ffi Python binding.

Run this first to confirm the binding and native library are installed and
matched. It exercises only the non-network APIs, so it needs no internet:

    python3 01_offline_check.py

If this fails with `InternalError("UniFFI ... mismatch")`, the generated
`contextvm_ffi.py` and the native library were taken from different releases
(see README.md).
