"""Catalog resource — WhatsApp Business catalog, products, and product sends.

Backed by ``src/modules/catalog/catalog.controller.ts``
(``@Controller('sessions/:sessionId')``). NOTE: the catalog controller is
mounted under the session root, so catalog reads are ``/catalog...`` while
product sends share the messages namespace
(``/messages/send-product``).
