Build me a polished online bookstore app where people can browse books, search by title or author, filter and sort results, view detailed book pages, leave reviews, save favorites, and add items to a cart that stays saved when they come back. I also want secure sign up and login, user profiles, order history, checkout with coupon codes, and a few membership plans with different perks and discounts.

Please include an admin area too, where I can add, edit, and remove books and categories, manage orders and user accounts, create coupons, and see basic sales stats with charts. Make the UI feel premium and cozy, with a modern glassy look, smooth animations, mobile friendly layouts, and dark mode. Use a backend and database so the data is real and persistent, and if you need to look up current docs or best practices online, go ahead.
