Build me a polished QR code generator web app that feels modern and fun, with a full page animated 3D look and a live QR preview. I want people to be able to make QR codes for text, links, email, phone, SMS, WiFi, vCards, and especially location links that work with any maps app. For maps, if someone pastes a Google Maps link, it should turn into a universal location QR automatically.

Let users customize the QR with colors, gradients, dot and corner styles, error correction, and an optional logo, then download it as PNG, SVG, or PDF. I also want a simple Supabase setup so it saves QR history, supports templates, batch creation from CSV, and tracks basic analytics like scan counts. Make it responsive for desktop and mobile, and keep the whole experience smooth and visually impressive. If you need to check current docs for anything, look them up online.
