   Divano - 3D Preview Layer  (2026, v1)
   Styles the lazy <model-viewer> modal opened by js/divano-3d.js,
   plus the reusable "Preview 3D" button (.dv3d-btn) and card
   badge (.dv3d-badge). Self-contained: defines its own tokens so
   it works even if load order changes. Deep-teal backdrop, tan
   accents - minimalist architect clarity, on brand.
