/**
 * Internal base class for every domain sub-client (tasks, projects, …).
 *
 * Not exported from the package — sub-clients are an implementation detail
 * of `TodoistApi`. Holds the three pieces of HTTP identity every sub-client
 * needs and exposes a typed accessor to feed the Sync API helper.
 *
 * The constructor takes a {@link SyncRequestContext} — the same record
 * shape used by `performSyncRequest` — so there is a single type describing
 * "the HTTP identity an SDK component needs", not two types that must stay
 * in sync.
