Farhan-Ansari-1/zelxon-coffee ? reverse-engineered prompt

Build me a coffee ordering web app called Zelxon Coffee.

I want customers to be able to browse the menu, sign in with Google, add drinks to a cart, and place an order for delivery or pickup. For delivery, save their name and address, let them enter a pincode or city, and if possible help fill in location using their browser location. I also want a simple loyalty system with ranks from Bronze up to Grand Master, plus cup count, streaks, progress, and a shareable rank card.

Please also include a basic admin area where I can log in with a username and password, manage products and images, view orders, change order status, see revenue, and review customer and city expansion requests. Use a clean coffee themed design that works well on desktop and mobile.

Make sure the app is ready to run locally with environment variables, and if you need to check current docs or APIs, look them up online.
