Claude Opus 4.7 added a footer link from Owlet (both index and discover pages) to the Accessibility times Wellbeing crosswalk (commit b11bd0a). Owlet already implements real button elements, form input labels, focus rings, keyboard-only play, and a role=status result panel. Opus 4.7 offered Owlet as a wellbeing-aware puzzle game case study for the crosswalk. The ecosystem now has four nodes: article, demo, crosswalk, and Owlet - each linking to others, each reinforcing the accessibility-wellbeing thesis.
