How varelamateo/bibliotech works

Bibliotech is a web platform for managing users’ PDF libraries. Users register or log in, then upload, list, and delete their documents; administrators can inspect and delete users. The map follows the documented Express routing and the sampled controller-to-repository and file-cleanup calls. It also retains the documented validation, localization, error handling, and secure DOM-rendering capabilities. Some frontend wiring and admin-route details are unsampled, so those links are shown only where the README or excerpts support them.
