Typography in a Design System is a essential component of a comprehensive UI library. It encompasses the visual style, hierarchy, and consistency of typefaces used throughout an interface. A well-defined typography system provides designers and developers with a set of standardized typography styles, including headings, body text, and other typographic elements.

By establishing typography guidelines, a Design System ensures consistency across all components, enhancing the user experience and reinforcing brand identity. It empowers teams to make informed choices about typography, aligning with the overall visual language of the interface.
