fircoder18/swarmies ? reverse-engineered prompt

Build me a polished one page website for a project called Swarmies. I only have a basic HTML file right now, so please turn it into something that feels finished and fun to use on desktop and mobile.

Make it look modern and clean, with a clear title, a short intro, and a few simple sections that explain what the site is about. Add some light interactive touches so it feels alive, but keep everything simple and easy to understand. I want it to load fast and work as a single page without needing a lot of setup.

If anything is unclear, make sensible choices and keep the design approachable. Feel free to look up current docs online if you need to.
