GNOME/papers ? reverse-engineered prompt

Build me a GNOME document viewer called Papers that feels clean and simple to use. It should open and read documents like PDF, DjVu, comic book archives, and multipage TIFFs, with a nice page view, zooming, scrolling, page navigation, search, and the ability to handle both single page and multi page documents smoothly.

Make it fit naturally into the GNOME desktop, with a polished app window, good keyboard shortcuts, and sensible file opening from the desktop and file manager. If there’s time, include thumbnail previews and a basic print or export flow if that makes sense for this kind of app.

I’d like it built so it can be compiled and tested from the repo, and if you need to look up current GNOME or Poppler docs online while wiring things up, go ahead. Keep the experience lightweight and dependable, like a modern document reader people would actually want to use every day.
