During August 2025, Fenny developed dark mode support for the Stargazer visualization in the gofiber/fiber repository, enhancing accessibility and user experience. The solution dynamically loaded SVG images based on the user's color scheme, ensuring seamless adaptation between light and dark modes. Fenny documented the new feature in the project’s README using Markdown, providing clear guidance for users and maintainers. The work was delivered as a focused, single-commit change, minimizing risk and complexity while laying the foundation for future theme-aware visualizations. This contribution demonstrated proficiency in documentation and user interface adaptation, with a targeted scope and careful attention to maintainability.
