## Key Features Implemented

- **Composition API style**: All stores use `defineStore` with arrow function syntax
- **Pagination support**: Each store with list data includes pagination state
- **Loading states**: All async operations track loading state
- **CRUD operations**: Materials, inbound, outbound, and users stores include create/update/delete
- **Category mapping**: Materials store includes category code to name mapping (A01-F05)
- **Filter support**: Logs store includes operation type and date range filters
- **Token persistence**: Auth store persists token and user to localStorage
