## Overview

Book Sanctuary is a PHP library-catalogue and borrowing application. Readers sign in, browse or search books, inspect a title, add it to their active reading list, return it, and review borrowing history. Administrators manage catalogue entries. The graph reflects the sampled page logic and the capabilities evident from the file tree; source for several action handlers and the database configuration was not sampled, so their internal behavior and uncertain wiring are not expanded.

Main entry points: [`bibliotheque.sql`](https://github.com/olmedo-ux/bibliotheque-reloaded/blob/main/bibliotheque.sql) (Library database), [`admin_panel.php`](https://github.com/olmedo-ux/bibliotheque-reloaded/blob/main/admin_panel.php) (Catalogue management), [`results.php`](https://github.com/olmedo-ux/bibliotheque-reloaded/blob/main/results.php) (Search catalogue), [`index.php`](https://github.com/olmedo-ux/bibliotheque-reloaded/blob/main/index.php) (Home and new books)
