Building a RESTful Creature Management System with Spring Boot and Vanilla JavaScript

I recently built a full-stack project called Bestiario, a creature management system designed to practice REST API architecture, relational modeling, and logical filtering. Instead of using a frontend framework, I chose vanilla JavaScript to focus on backend structure and API clarity. The repository is open for anyone who wants to explore, practice, or extend it.
