What it does
This class provides pagination options for product listing pages in Magento 2's catalog.
Developers use it as a source model in system configuration to define how many products can be displayed per page (e.g., 12, 24, 36).
It converts a comma-separated string of page size options into an array format suitable for admin dropdown menus.
