Q: We are building an e-commerce platform.
Explain your state management architecture.
A:
1. UI State (modals, active tabs, form inputs): React `useState`.
No need to clutter the global store.
2. Server State (products list, inventory data): `RTK Query`.
This handles all caching, deduplication, and loading spinners automatically.
3. Global Client State (shopping cart, current user auth): `Redux Toolkit`.
This data is accessed by hundreds of components and needs predictable,
global synchronization via standard Redux Slices.
