Worked on enhancing the nix-security-tracker repository by improving brand consistency and user interface polish. Focused on aligning the header and footer with NixOS brand colors, introducing an accessible color variable, and embedding the NixOS logo in the header to strengthen visual identity. Utilized CSS and HTML for layout and styling adjustments, while leveraging Nix to fetch and integrate official branding assets during the build process. Ensured that all changes maintained accessibility standards and passed CSS linting. The work resulted in a more cohesive and accessible user experience, with improved brand recognition and reliable asset management across the application.
