During June 2025, this developer enhanced the Sage/carbon repository by refactoring the Note component to render its title as an h3 element, improving both accessibility and SEO in line with WCAG guidance. The work involved updating the React implementation and TypeScript definitions to ensure semantic markup when the title is provided as text, while maintaining API compatibility. Comprehensive tests were revised to validate the new behavior and confirm accessibility improvements. The focused change was delivered with a clear commit history, demonstrating attention to detail in component development and front-end engineering using JavaScript, React, and TypeScript throughout the process.
