/**
 * The read-only FHIR R4 face under `/api/fhir`, against the real database and
 * through the real API kit.
 *
 * What a client relies on here:
 *   - the CapabilityStatement describes the instance answering, and every
 *     interaction it advertises has a route behind it;
 *   - each resource route serves the caller's own stored values, as the
 *     owner's saved report selection scopes them, and never another
 *     account's: a foreign id answers a `not-found` OperationOutcome;
 *   - a narrow token passes with the `fhir:read` scope the routes declare and
 *     is refused with any other, and the `fhir:read` token reaches nothing
 *     outside this face;
 *   - `Patient/$everything` carries every family the document export carries,
 *     with references that resolve inside the response, and asks a browser
 *     session for a recent sign-in.
 *
 * The module gate has its own file (`fhir-module-gate.test.ts`).
