Before we dive in, quick word: everything you're about to read gets built, tested, and taken further inside Bestapps Academy, our Skool community. It's where we drop the actual skills, walk through the builds live, and troubleshoot each other's projects, so instead of just reading about a 3D hero, you ship one with people looking over your shoulder. If this guide clicks for you, that's the room where it goes from "interesting" to "in production."
