Problem

Implement a Paginator class that takes a list of pages (each page is itself a list of items) and iterates through all items across all pages in order. It must support the Python iterator protocol (__iter__ and __next__). (The harness calls list(Paginator(pages)) and expects the flattened item sequence.)

Summary

Nobody loads everything at once.
