Living Documentation and Usage Guidelines

A component without clear usage documentation is a liability. World-class design system portals (like Shopify Polaris or IBM Carbon) provide:

• Do's and Don'ts: Clear visual side-by-side examples illustrating proper vs. improper usage.
• Accessibility Notes: ARIA roles, required keyboard shortcuts, and screen reader announcements.
• Content Guidelines: Recommended character counts and voice guidelines for button and modal copy.
• Interactive Code Playground: Embedded live Storybook or sandbox viewports where engineers can test props in real time.
