adityathegit/small-library-app ? reverse-engineered prompt

Build me a simple library app that runs in the browser using plain HTML, CSS, and JavaScript.

I want a clean page where I can add books with basic details like title, author, and maybe number of pages or whether I’ve read it. After I add a book, it should show up in a neat list or cards on the page. I should be able to remove a book and update whether it has been read. Please make it look good on both desktop and mobile, with a simple modern layout.

Keep it lightweight and easy to use, with everything working on the front end. If it helps, use the browser storage so the list stays there after refresh. Make the UI feel polished, with a form at the top and the library list below. If you need to check anything current, feel free to look up the best approach online.
