Field notes
The project treats a rendered reference page as a source of testable values rather than as an image baseline. Its contract can include box geometry, computed colour and typography, interaction-state changes, root custom properties, and animation keyframes, while a stated GitHub Action checks preview deployments in pull requests. The homepage reports 1,066 assertions per page and names Node 22.12+ as a requirement.
