/* ============================================================================
   VISUALIZATION STYLES - NOW SELF-CONTAINED
   ============================================================================
   The following styles have been moved to visualization/orthogonal-radial-tree.js
   to make the visualization completely self-contained:

   - .ort-node-group (previously .node-group)
   - .ort-node-line (previously .node-line)
   - .ort-node-circle (previously .node-circle)
   - .ort-node-text (previously .node-text)
   - .ort-node-desc (previously .node-desc)
   - .ort-node-duedate (previously .node-duedate)
   - .ort-link (previously .link)
   - .ort-cycle-link (previously .cycle-link)
   - .ort-label-text (previously .label-text)
   - .ort-center-node (previously .center-node)

   The visualization now injects its own CSS on first instantiation.
   This allows the visualization to be swapped with a different implementation
   without any CSS modifications required.
