adi1090x/termux-desktop ? reverse-engineered prompt

Build me a one command setup for Termux on Android that turns a fresh install into a nice looking Linux desktop I can open with a VNC app.

I want the script to install the needed packages, set up the desktop, create a start command like startdesktop, and handle VNC password setup during install. It should also make backups of any files it replaces and have an uninstall option that cleans everything back out. Use a lightweight desktop feel with a window manager, a launcher, a menu, and some basic apps like a file manager, editor, browser, terminal, and common command line tools.

Make it look polished by default, and include a few different themes or styles I can switch between from the desktop menu. If it needs extra Termux or VNC info, look up the current docs online and keep it working as simply as possible for someone who is not very technical.
