Worked on the espressif/blowfish repository to deliver dynamic theming support for SVG logos, focusing on seamless day and night mode transitions. The implementation involved updating the src attribute of img.logo elements and enabling real-time updates of SVG content within span.logo containers, ensuring that branding remained consistent across light and dark themes without requiring page reloads. This feature was developed using JavaScript and HTML, applying front end development skills to create a maintainable, theme-aware code path. The approach reduced manual intervention for theme changes and provided a foundation for future enhancements in appearance management within the project.
