In one sentence
MainScaffold is the post-paywall shell with indexed tabs and optional bar
hiding.
Current behavior
Stateful scaffold with initialIndex and an inline bottom navigation
(when enabled). Active tabs: Home, Learn Videos, Rewire Brain, Community,
Profile. Lifecycle observers mark onboarding complete for authenticated users
when appropriate. The older
lib/features/app/presentation/widgets/bottom_navigation.dart file is not the
active tab builder.
Current state
