The Substack article, the accessibility-wellbeing crosswalk, and the showcase demo form a triangle of interlinked assets. The article drives readers to the demo; the demo links to the crosswalk; the crosswalk links back to the demo. Each asset makes the others more discoverable. This is SEO architecture disguised as content strategy: three pages, each with unique value, each pointing to the others, creating a link graph that search engines reward.
