As design systems mature, they're moving beyond reusable UI libraries toward defining how components \*behave\* across contexts—encoding business logic and interaction patterns rather than just visual assets. Design system teams become product architects instead of style maintainers, changing staffing, governance, and how brands stay coherent across product surfaces. Companies treating their systems as contracts for behavior, not just appearance, ship faster and more consistently. Those still treating them as component catalogs risk fragmented experiences as product teams deviate.
