What it does
This interface defines the contract for product attributes in Magento 2's catalog system.
It extends EavAttributeInterface and declares constants for commonly used product attribute codes like SKU, price, name, description, and weight.
Developers use this interface when working with product attribute data through APIs or when creating custom implementations that need to handle product attributes programmatically.
