Exceptions (``quantum_safe.exceptions``)
=========================================

All exceptions inherit from :class:`~quantum_safe.exceptions.QuantumSafeError`
so you can catch the entire hierarchy with a single ``except`` clause.
Every exception carries a machine-readable ``code`` string for programmatic
handling.
