nikunj-alt/ecobrew ? reverse-engineered prompt

Build me a polished coffee shop storefront called EcoBrew for a school fair project.

I want a clean, modern website where people can browse coffee products, see product details, send a contact message, and place an order. It should feel like a real small e commerce site, with a nice home page, product listing, product pages, and a simple checkout or order flow that saves data to Supabase.

Please also include a basic sign in experience for customers and an admin area for managing products, orders, and contact messages. Use secure server side handling for anything private or write based, and make sure the public app can only view products and submit contact forms.

Use Next.js with TypeScript and Tailwind, and make it look good on mobile too. If you need current docs for Supabase or Google sign in, look them up online.
