Build me the frontend for an online store called Invern Spirit, using SvelteKit.

I want a polished e commerce website where people can browse products, view product details, add items to cart, and move through checkout smoothly. It should feel clean, modern, and easy to use on both mobile and desktop, with a strong focus on speed and a nice shopping experience.

Please wire it up so it can talk to the backend through environment variables, and make sure the app works nicely with the local functions server for any backend for frontend needs. Use the existing project setup, keep things organized, and include the usual pages and states people would expect, like loading, empty, and error views. If you need the latest guidance for SvelteKit or any related docs, look it up online first.
