A design system should not be a gallery of perfect components that only works in a presentation. It should help a team answer ordinary questions quickly: which state belongs here, how should this behave on a small screen, and what happens when the content is longer than expected?
The strongest systems connect visual rules to implementation. Tokens describe colour and spacing, components document interaction states, and accessibility requirements remain visible before code review.
This shared language reduces rework. Designers spend less time redrawing familiar patterns, engineers inherit fewer ambiguous states, and customers experience a product that feels coherent from one task to the next.
