Build me a clean, fast web app for an online community platform where people can chat, play games, watch videos, and use a simple proxy tool in one place.

I want the main page to feel lightweight and easy to use, with a simple layout that works well on low memory devices and loads quickly. Include sections for chat, a big games library, video access, and a few extra tools or apps. Make it feel like a real community site, not a cluttered dashboard.

It should also have a dark mode, a search page, a player page for launching games or media, and a basic account or auth flow if needed. Make it responsive, include the usual site extras like a service worker and manifest, and keep the design polished but minimal. If you need current docs for any libraries or browser features, look them up online first.
