Aviral2002/3dJournalWeb ? reverse-engineered prompt

Build me a 3D journal web app where I can open a beautiful virtual book, click through pages, and write journal entries directly on them.

I want the book to feel immersive, with smooth page turning, subtle floating motion, nice lighting and shadows, and a calm classical look, kind of like a philosophical notebook. The text I write should save automatically in the browser so if I come back later my entries are still there. It should also be easy to move between pages with simple on screen controls, and I should be able to rotate and zoom the book with the mouse.

Please make it feel polished and responsive, with the writing experience staying clean and readable. If you need to check current docs for the 3D or state libraries, feel free to look them up online while building it.
