Build me a full ecommerce site with both the frontend and backend working together.

I want customers to be able to browse products, see product details, add items to a cart, and go through a simple checkout flow. It should also have an admin side where I can manage products and basic store content. Make it feel like a real online store, clean and simple, with good looking pages made using HTML and CSS.

Use Node.js with MongoDB for the server and data storage, and build the pages with Handlebars. Keep the project organized so it is easy to run and update later. If you need current docs or best practices for anything, look them up online.

Please make sure the app starts cleanly, the main pages are wired up, and the whole thing feels like a complete ecommerce project rather than just a demo.
