Build me a free browser based Claude chat app that I can self host with no backend or server costs. I want it to feel polished and similar to the official Claude experience, with a clean chat screen, streaming replies, light and dark mode, and recent conversations saved in the browser.

Use Puter.js so the app connects to Claude through the user’s own Puter account. The first time someone sends a message, show a friendly login or permission flow and explain that popups need to be allowed. Keep everything in plain HTML, CSS, and JavaScript.

Please include nice handling for code blocks. If Claude returns code, show it as an artifact card with syntax highlighting, copy, download, and an HTML preview when possible. Make it easy to run locally with a simple Python web server, and include a Windows run_server.bat that opens localhost automatically. Look up current Puter.js docs online if needed.
