GRVYDEV/marky ? reverse-engineered prompt

Build me a lightweight desktop markdown viewer called Marky for macOS and Linux.

I want to be able to run it from the terminal like marky README.md to open a single file, or marky ./docs/ to open a whole folder as a workspace, and when I launch it with no arguments it should restore my last session. It should feel fast and native, with live reload whenever the markdown file changes on disk.

Make the markdown render nicely, including tables, task lists, code blocks with syntax highlighting, math, and Mermaid diagrams. Add a sidebar for folders, a command palette for quickly finding files, and simple shortcuts for opening files, adding folders, and searching in the page. Support light and dark mode, and make sure any HTML is safely sanitized before showing it.

If you need to check current docs for the libraries or Tauri setup, go ahead and look them up online.
