/**
 * Lazy initializer for the Feature Flags SDK.
 *
 * NOT registered in AndroidManifest.xml. Application.onCreate() defers triggering
 * this initializer by 500 ms so it never competes with first-frame rendering or the
 * immediately-needed Analytics / PerfMonitor SDKs.
 *
 * FakeFeatureFlagsSdk.isEnabled() returns false (the default) for any flag until the
 * background coroutine completes — the UI is never gated on this SDK being ready.
