Worked on stabilizing the front-end user interface for the Sonarr/Sonarr repository, focusing on consistent rendering across both desktop and mobile devices. Addressed a cross-device issue with the Season Action Menu by implementing conditional maxHeight logic, which prevents layout regressions when switching between device contexts. Improved the reliability of fanart rendering on the Series Details page by adjusting the header’s z-index, eliminating visual gaps and layering issues. Utilized React for component logic and applied CSS and TypeScript to manage styling and type safety. The work centered on bug resolution, enhancing user experience and interface stability without introducing new features.
