     .cc-lineage                      the component (a container-query root)
       .cc-lineage__toolbar           zoom - / level / + · Fit · Center · Expand
       .cc-lineage__viewport          the scroll area (pan = native scrolling)
         .cc-lineage__sizer           takes the scaled size, so scrollbars match
           .cc-lineage__stage         unscaled layout, scaled with transform
             svg.cc-lineage__links    decorative connectors behind the cards
             .cc-lineage__gen--parents / __root / __gen--offspring
       .cc-lineage__hint              how to move / zoom on this device

   Card sizes come from the script as --lin-card / --lin-root / --lin-gap /
   --lin-pad / --lin-cols, stepped by the component's own width. Brand tokens
   come from css/styles.css. Notes: docs/PRODUCT_LANDING.md ("Lineage graph").
