### Important

Do not give me only an explanation. **Build the complete working website code.**

Return the complete code in one HTML file that I can save as `index.html` and open directly in a browser.

Make the final result look like a professional real-world e-commerce website rather than a basic demo.

I can also create a **complete working e-commerce website from this prompt** and give you the HTML/CSS/JavaScript code.
