Harshad focused on front-end stability in the Stirling-Tools/test-dont-use repository, addressing a navigation issue where the collapsed menu state failed to persist after page reloads. Using JavaScript and CSS, Harshad recalculated the feature group container’s maximum height to match its full scroll height, ensuring the navigation layout remained consistent with user expectations. This targeted bug fix improved the user experience by reducing confusion and maintaining predictable navigation behavior across sessions. The work demonstrated a practical application of front-end development skills, with attention to detail in user interface state management, though the scope was limited to a single, well-defined issue.
