sumatrapdfreader/sumatrapdf ? reverse-engineered prompt

Build me a fast Windows document reader that can open PDF, EPUB, MOBI, CBZ, CBR, FB2, CHM, XPS, and DjVu files.

I want it to feel simple and lightweight, with a clean reader view, easy page navigation, zooming, search, and a sidebar for things like thumbnails or table of contents when the file supports it. Make it behave like a no fuss desktop app people can use right away, with solid keyboard shortcuts and a focus on speed and reliability.

Please keep the look and behavior close to a classic Windows app, and make sure it can handle opening files from the desktop and dragging in documents easily. If you need to check anything about supported formats or best practices, look up current docs online.
