SalesModelInterface

What it does

This interface defines a contract for accessing sales model data (like quotes or orders) in a standardized way for payment processing.

Developers use this when building payment integrations that need to retrieve cart totals, items, tax, shipping, and discount information without knowing whether they're working with a quote or order object.

It provides a unified API to access financial data from different sales entities.
