This creates living documentation that is easy to review and keep up to date. 3. **Testing appearance and behavior** Supports visual tests (for example, snapshot tests), accessibility checks, and automation of user scenarios. 4. **Team collaboration** Simplifies interaction between designers, developers, and QA, everyone sees how each component should look and behave. 5. **Design systems and reusable libraries** Ideal for building scalable design systems, where clarity, repeatability, and control over the state of every interface element matter.For the reviewerNote to the moderator (optional)Visible only to the moderator.
