Worked on moltbot/moltbot to enhance UI consistency and accessibility, focusing on improving the user experience in light mode. Addressed visual friction between themes by implementing visible scrollbar styling for the root element and applying dark thumb overrides using CSS. Fixed a regression introduced by an automated suggestion by reverting to a reliable descendant selector approach, ensuring the scrollbar rendered correctly in light mode. Conducted regression QA to verify consistency and accessibility across UI components. Leveraged skills in CSS, UI Design, and UI Development to align the interface with the design system, resulting in a more cohesive and accessible user interface.
