ScopeInterface
Magento\Store\Model\ScopeInterface
What it does
This interface defines constants for Magento's scope levels (stores, groups, websites) used throughout the system for configuration, pricing, and content management.
Developers use these constants when working with scope-specific configurations, retrieving store data, or implementing features that need to operate at different hierarchy levels.
It ensures consistency when referencing scope types across the entire Magento application.
