A production design system speeds up delivery and keeps accessibility a default. Pair unstyled accessible primitives with semantic tokens and you get a foundation that scales across products.
Accessible primitives
Primitives should own focus traps, keyboard navigation, and ARIA roles. You style the surface; behavior stays consistent out of the box — so every product inherits the same interaction contract.
Accessibility works best when it is the default path, not a checklist at the end.
Tokens and theming
Keep colors, radius, and spacing in CSS variables. Light and dark modes swap tokens without shipping a theme runtime — consumers stay in control of the look while components stay portable.
Conclusion
Accessible behavior, flexible styling, and low runtime cost make a stack teams can adopt once and reuse everywhere.
