Build me a simple web chatbot that can answer questions from its own knowledge, and also look things up on the web when it needs to. I want the chat to feel modern and conversational, with streaming responses so I can see it think step by step, support for markdown in replies, and clear citations whenever it uses web results.

Please make the app split into a backend and a frontend, with a local dev setup that is easy to run. The backend should handle the chat logic, memory across turns, and the web search and page extraction part. The frontend should be a clean chat interface where I can type questions and see responses come in live. If helpful, use the current docs online for any libraries or best practices.

Keep it simple and polished, with sensible defaults, environment variables for the API keys, and everything wired together so it works end to end.
