 * live in those collaborators; callers reach the behaviour they need via
 * {@see oauthStore()}, {@see searchAnalytics()}, and {@see renderer()}.
 *
 * Config constants are re-exported here as a stable reference surface for
 * callers and tests (the values themselves live in ABJ_404_Solution_GscConfig).
