Codecrafter32/zerodha1 ? reverse-engineered prompt

Build me a Zerodha style trading clone with a polished marketing landing page and a separate trading dashboard.

I want the dashboard to show holdings, positions, orders, and a simple buy and sell flow that actually saves data to a real database. The app should feel like a real stock trading product, with a clean modern UI, an equity and margin summary, and basic order placement working end to end. Please make it full stack, with a backend API connected to MongoDB, and two React based front ends, one for the public site and one for the dashboard.

Keep it simple and realistic, this is a clone for demo purposes, so no login system is needed. If you need to check current setup details or best practices, look up the latest docs online. Also make sure it can run locally and be easy to deploy separately for the landing page, dashboard, and backend.
