paulocarvalhof/Dracon-OS ? reverse-engineered prompt

Build me a lightweight desktop style Linux environment for Termux that opens through VNC, with an Alpine inspired look and a simple installer so someone can go from a fresh clone to running dracon start and connecting in RealVNC Viewer on localhost.

I want it to feel like a small phone friendly operating system, with a bottom taskbar, start menu, open windows, and a clock. Add a way to switch between several color themes, plus a task manager to see and stop stuck apps. Include a game hub with a few simple terminal games like Snake, Tetris, and Pong, and a separate game store area. Also add a basic account login and registration flow with local session saving, and a command that can fix broken shortcuts if something stops working.

Make it easy to install, easy to update, and make the whole thing feel polished and usable, not just a script collection. If you need to check current docs for Termux, VNC, or Firebase details, look them up online.
