Custom E-Commerce Site Prototype

I need a ground-up, code-only eCommerce prototype for a premium equestrian brand. The store will sell physical products and eventually evolve into an immersive, castle-themed experience with animated smoke effects, 3-D product views, and multiple AI chatbots (“Mr Jhon” for general navigation, “Mr F Freaky” for R&D items, and “Mr Elton” for checkout and loyalty).

Because we’re starting lean, this first phase should deliver:
• A responsive homepage, product page, and secure checkout coded from scratch (no Shopify, WooCommerce, or Magento).
• Hooks for product recommendations, user reviews, and loyalty points so we can bolt those modules on later.
• A lightweight AI chatbot proof-of-concept: greet visitors, guide them to a product category, and hand off to checkout.
• Placeholder animation for the vault entrance—just enough to demo the idea that elite customers can unlock it with a code.
• Clean, elegant castle-inspired styling, animated logo intro, and subtle smoke overlay so we can judge the visual direction.
• Basic customer data capture to our database: name, flag icon, and GPS location (if permission granted).

Keep the code well-commented and modular so we can expand into full 3-D views, bundle offers, order tracking, and additional bots in later milestones. I’m open to your preferred modern stack—just make sure it’s secure, fast, and easy to scale.
