Prompt

We need an official design system specification for our primary action button component. Please generate complete implementation guidance starting with the component's context and objectives, followed by applicable foundation tokens. Then detail the component's anatomy, visual states, and responsive behavior. Be sure to include testable accessibility acceptance criteria, microcopy guidelines, anti-patterns to avoid, and a developer QA checklist to use during code reviews.
