…management WHAT: Remove AppStateProvider god object, service locator pattern, and complex UI hierarchy to implement clean direct service-to-UI communication architecture WHY: The previous architecture had become over-engineered with a 428-line AppStateProvider managing all state, service locator pattern creating hidden dependencies, and 1000+ line UI components violating single responsibility principle. This complexity was causing bugs, making the app hard to maintain, and preventing incremental feature development HOW: Deleted all complex state management components including AppStateProvider, ServiceLocator, and multi-responsibility UI widgets. Removed unnecessary services and models not needed for core audio functionality. This creates a clean foundation where services own their data and UI components directly consume service streams without intermediary coordinators
