Insight: Design systems are maturing from documentation-and-hope approaches to enforceable infrastructure with validation at design-time, build-time, and runtime. Teams can encode required children, forbid bad prop combinations, and use TypeScript/linting to catch errors earlier. These enforcement mechanisms scale particularly well as AI agents begin producing UI — validation rules that protect against human mistakes also protect against AI mistakes.

Detail: The publication frames this as design systems moving beyond "surface-level consistency" into real infrastructure. Token implementation guides (mapping from Figma with primitive, semantic, and component layers), making design decisions falsifiable (not just documented), and deprecation strategies are all signs of maturation. The community is producing fewer hypotheticals and more "this is where it breaks, and this is what we did about it."
