Build me a clean, modern landing page for AT4K Launcher, the Android TV home screen app.

I want it to feel simple, fast, and privacy friendly, with a TV style design that matches the app. Include a strong hero section, a short explanation of what the launcher does, clear feature highlights, supported devices, and an easy download area with buttons for Google Play and the APK. Add sections for installation, how to set it as the default launcher, and basic troubleshooting for devices that keep switching back to the stock home screen.

Please also include links to the official website, Reddit community, and a place for discussions or support. Make it work well on mobile and desktop, keep the copy friendly and easy to read, and make sure the page looks polished without feeling cluttered or ad heavy. If you need current details, look them up online and use the latest info.
