Antoine Giasson enhanced the visual consistency of modal components in the kronostechnologies/design-elements repository by implementing a Modal Border Radius Consistency Enhancement. He updated the border-radius CSS variable from var(--border-radius-2x) to var(--border-radius-4x), aligning the components with the DS-1548 design system and centralizing token usage for improved theming. Working primarily with React and leveraging both JavaScript and TypeScript, Antoine encapsulated the change in a single, review-friendly commit, minimizing the surface area and simplifying code review. This focused update addressed a specific UI design need, contributing to a more cohesive and maintainable front end architecture.
