sarveshbhoyar22/altstore ? reverse-engineered prompt

Build me a clean online store for premium T shirts and oversized clothing called AltStore.

I want a modern storefront where people can browse products, filter by category or size, view product details, add items to cart, and place an order with a simple checkout flow. Please include a nice home page, product listing, product detail pages, cart, and a smooth mobile friendly design that feels premium and streetwear focused.

If it makes sense, set it up so orders can be paid online, order confirmations can be emailed, and product or order data can be stored securely in the backend. I also want a basic admin area where I can add or edit products, manage stock, and see orders. Use the existing app structure here and make the whole thing polished, responsive, and ready for real use. Look up current docs online if you need to.
