Worked on enhancing the pacalso-jjc/2425-2nd-cc3-1e-rpg repository by building and refining a Mermaid class diagram to document the Archer class and its relationship to Classification. Focused on improving architectural clarity, the work involved removing the HP stat from the diagram, updating inheritance indicators, and correcting Markdown syntax to ensure accurate rendering. Emphasized maintainability and onboarding by delivering clear, well-structured documentation without introducing runtime changes. Utilized skills in diagramming and documentation, leveraging Markdown and Mermaid to create a resource that reduces ambiguity and supports future development. The contribution addressed documentation needs rather than direct feature or bug fixes.
