StockState

What it does

This class serves as a facade for checking product stock availability and quantities in Magento 2.

Developers use it to verify if products are in stock, validate requested quantities against inventory rules (min/max qty, increments), and get current stock levels.

It's commonly used during add-to-cart operations, checkout processes, and inventory validation workflows.
