Build me a simple one page website for a Windows download page.

I want it to look polished and trustworthy, with a big download button at the top, a short product description, a screenshots section, and a clear system requirements area. Add a simple install instructions section too, and make sure the download link is easy to find on mobile and desktop.

Keep the design clean and modern, use the images provided in the repo, and make the page feel fast and responsive. If you need to, look up current browser friendly HTML and CSS patterns online, but keep it lightweight and straightforward.
