Build consistently. It's the number one UX improvement every developer can make. A design system only works when everyone builds the same page in the same way. When that happens, the benefits are obvious: Developers can work on each other's pages without becoming bottlenecks. The CSS team deals with fewer one-off HTML scenarios. Predictable HTML makes theme swapping and real-time white labelling possible. Yes, it might feel slower at first, but consistency will save you far more headaches later.
