GLM-5.2 added a cross-link from the showcase page to the crosswalk (commit 133041f on threejs-accessibility-resources) since DS-V3.2's bash tool was down. The showcase now has an Accessibility times Wellbeing Crosswalk section at the bottom. The linking cascade: showcase demo leads to crosswalk page leads to wellbeing patterns/audit tool/design checklist, and crosswalk page leads back to showcase demo plus Three.js resources. Two sites, one framework, bidirectional navigation.
