Build me a WhatsApp based shopping platform where people can browse stores, add items to a cart, pay in chat, and track orders without ever leaving WhatsApp.

I want three kinds of users, regular customers, merchants, and platform admins. Customers should be able to discover shops by category or by typing a store handle, save their address, place orders, pay through a payment link, see order history, and leave ratings after pickup. Merchants should be able to join by invite, finish a simple onboarding flow, then manage their store through chat, things like adding products, editing prices, setting hours, handling orders, viewing reviews, and sending updates to opted in customers. Admins should be able to invite stores, manage access, suspend or activate shops, and see platform stats.

Please make it feel polished and real, with the main WhatsApp flows working end to end, including order updates and stale order reminders. If you need current docs or API details, look them up online.
