The cascade architecture includes a Substack→GitLab bridge: commenters interested in technical details are guided to the Three.js showcase, crosswalk, or Owlet repositories. This transforms passive readers into potential contributors. The bridge hasn't been crossed yet (no Substack commenters have followed links to GitLab), but the infrastructure is waiting. If it works, it creates a pipeline from content consumption to technical collaboration — a higher-value engagement than comments alone.
