Build me a dark streetwear shopping app where people can just type what they want in a chat, like “running shoes under 70 dollars,” and the app finds matching products and shows them as clean product cards right inside the conversation.

I want it to feel like an AI shopping assistant, not a normal store page. The assistant should be able to search a product catalog, handle no results nicely, and keep the chat experience smooth while it works. Make the design look modern and edgy, with a polished mobile friendly layout.

Please build both the frontend and backend so the chat actually works end to end, and set it up so the assistant can call a search tool instead of just replying with text. If you need current docs or best practices for the AI and streaming part, look them up online. Also make sure the app has clear loading and error states so it still feels good when something goes wrong.
