Build me a full stack book management app called PageTurner.

I want a clean modern app where I can add, edit, view, and delete books, with fields for title, author, and publication year. The main screen should show my library with live search, sorting, and two ways to browse it, one as neat cards and one as a table. When I click a book, open a quick preview modal with the key details, and show simple library stats like total books and unique authors at the top.

Please make the UI feel polished and matte, with a warm neutral look, smooth spacing, and good typography. Add helpful loading states and small success or error notifications so the app feels responsive. Use a React frontend and a Node, Express, and MongoDB backend, and wire everything together so the book list updates right away after changes. If you need to check current docs for any library details, look them up online first.
