Build me a modern streetwear e commerce marketplace where buyers can browse products, filter by size and color, add items to cart, and check out securely with Razorpay. Sellers should have their own dashboard to create and manage products, upload multiple images, set different prices and stock for each variant, and see their inventory and orders. Include secure login with email and password, Google sign in, password reset with OTP, and separate access for buyers and sellers.

I want the app to feel polished and production ready, with a clean responsive storefront, protected routes, session safe auth cookies, and automatic order confirmation emails to both the buyer and seller. Please make sure inventory updates happen correctly after payment, and if payment fails the stock does not get messed up. Use a simple REST backend with a React frontend, MongoDB for data, and look up current docs online if you need to.
