Harmno/Termux — reverse-engineered prompt

Build me a Termux customization project for Android called ZorkOS. I want someone to clone it, run one install command, restart Termux, and have their plain terminal turn into a flashy cyberpunk setup with colors, fonts, animations, themes, plugins, and a nice menu to change things later.

It should work without root and use shell scripts for Bash and Zsh, with Oh My Zsh support and lots of selectable Zsh themes. Include a customizer script that lets users pick themes, open feature modules, and switch modes like a hacker style screen. Please make the installer friendly, show clear progress messages, set up configs and assets from the repo, and avoid breaking existing Termux settings if possible by backing up old files first.

Add a polished README with simple copy paste install commands, screenshots section, and a short explanation for normal Android users. Look up current Termux docs online if you need to.
