"""
Healthie GraphQL client service.

Provides authenticated GraphQL queries/mutations against the Healthie API.
Returns parsed JSON responses. Only the generic query() entry point is used
in-repo (intake webhook consumers); form-management/upload helpers that lived
here had no call sites and were removed — intake_app has its own client for
the FastAPI-side flows.
