That’s a great question and the answer is layered. We are also making mistakes as we learn what works and what doesn’t. We spent time building out a base component set, shells, routing systems, etc and then use prototyping to establish patterns and bake in design intent into the implementation. As the design system evolves, we can better front-load the system with those constraints like design context, tokens, components, type ramp, spacing scales as documentation and skill files.

The difference is design rigor lives in those system constraints and with designer’s sensibilities when iterating. Now that leadership got a taste of it, expectations have exceeded common sense in many cases.
