On a cold start the consent flow is still running when home first builds, so createBanner returns null and the slot stayed empty until a rebuild. AdService now exposes an isReady ValueNotifier; BannerAdSlot listens and retries its load once MobileAds finishes initializing. Verified: analyze clean, 169 tests green.
