Worked on the HGustavs/LenaSYS repository to enhance UI consistency and maintainability through targeted CSS and front end development. Over two months, introduced standardized box-shadow variables in the CSS, refactoring shadow definitions to enable consistent styling and simplify future theming across the interface. Addressed a critical box-shadow bug, reducing visual inconsistencies and supporting a more robust design system. Additionally, centralized the purple icon color filter by implementing a dedicated CSS variable, eliminating duplication and streamlining color transformation logic. These changes improved maintainability, reduced the risk of regressions, and ensured a more cohesive user experience throughout the LenaSYS platform.
