"""Config package facade for get/set/load and test resets.

``get_config()`` is a process-wide live snapshot. On-disk schema, Settings
field metadata, and the resolver live in ``transcriptx.core.config``. Hydrate
this facade via ``apply_project_config_to_live_facade`` at app start and after
Settings save. New Settings knobs must land on a Pydantic model (or the frozen
non-pydantic baseline), not as dataclass-only fields.
