During the month, contributed to the LuccaSA/lucca-front repository by developing a checklist modifier for the Checkbox component, aimed at improving UI consistency and supporting checklist workflows. The work involved extending the design system’s capabilities through Angular component development, with a focus on CSS and SCSS for styling and TypeScript for input handling logic. Documentation was updated to guide usage of the new modifier, ensuring alignment with design-system standards. No major bugs were reported or fixed during this period. The feature enables faster assembly of checklist-related interfaces and promotes a more consistent user experience across front-end applications using this library.
