surjolive/moviebox ? reverse-engineered prompt

Build me a clean, polished GitHub repo for a premium Android APK release called MovieBox Premium.

I want the page to feel professional and easy to use, with a strong README, a nice hero banner, app icon preview, and a screenshot gallery. It should clearly explain that the latest APK can be downloaded from the release page, then give simple install steps for Android users, including what to do if they need to allow installs from unknown sources.

Make the README feel like a real product page, with a short intro, what is included, app highlights, release notes, supported devices, and a brief security note about side loading. Use the existing assets for visuals and keep the design dark, premium, and tidy.

If you need current GitHub README or release formatting details, look them up online first.
