ScopeInterface
Magento\Store\Model\ScopeInterface
What it does
This interface defines constant values for Magento's scope system, which determines the level at which configuration settings apply - stores, groups, or websites.
Developers use these constants when retrieving or setting configuration values to specify whether a setting should apply at the store view, store group, or website level.
This is fundamental for managing multi-store configurations and ensuring settings are applied at the correct scope.
