charmbracelet/glow ? reverse-engineered prompt

Build me a polished terminal app for reading Markdown, something that feels nice to use instead of plain cat or less. I want it to work in two ways. First, if I run it with no arguments, it should open a simple text UI where I can browse Markdown files in the current folder and subfolders, or in the current git repo, then open and read them with familiar pager style keyboard controls and a help screen.

Second, I want a normal command mode where I can pass a local file, pipe Markdown in through stdin, or point it at a GitHub, GitLab, or direct web URL and have it render nicely in the terminal. Please support word wrapping, optional paging through my preferred pager, and automatic light or dark styling with a way to choose a style manually or load a custom JSON theme. A config command and config file for saved defaults would be great too.

Keep it clean, fast, and cross platform. Look up current docs online if you need to.
