System Goals
Design systems reduce decision cost. Accessibility must become a default property not a afterthought QA checklist.
Semantic Primitives
Abstract ARIA roles & relationships within components (like tabs, dialogs) exposing simple props or classes.
Focus Management
Enforce focus traps & return focus on dismiss. Provide skip links and maintain logical tab order.
Color & Contrast
Tokenize color roles (bg, text, accent) and run contrast assertions in CI for critical pairs.
Documentation
Embed copyable examples with keyboard interaction notes and dos/don'ts.
Governance
Track adoption coverage: % of UI driven by system primitives vs ad-hoc bespoke components.
