Ahmadibrahiim/Website-downloader ? reverse-engineered prompt

Build me a simple web app that can take a website URL and download the full site for offline use, including the HTML, CSS, JavaScript, images, and other page assets.

I want a clean page where I can paste a link, start the download, and see clear progress while it runs. When it is finished, it should package everything into a zip file and send it back so I can save it on my computer. Make sure links get converted so the downloaded site still works offline, and keep the download limited to the site I entered.

Use Node.js for the backend, and make it work in a way that feels like a real production tool, with a simple front end and live updates while the download is happening. If you need to look up current docs online for any library or hosting detail, go ahead and do that.
