The ProductPageHub class acts as a high-level manager for interacting with multiple product pages simultaneously. While each page retains its own state and can be accessed individually, all pages share a single client session and a common task runner for efficient data updates.

API of ProductPageHub is similar to the one of the ProductPage class. Studying the latter is recommended before proceeding with the hub.
