   --pill-half  : half the pill height, anchors the bar at each pill center.

   --node-gap   : margin-bottom between nodes.
   --bar-width  : thickness of the vertical bar.

   Bar segment math (::after on each node):

     bottom = -(--node-gap + --pill-half)   → ends at NEXT pill center
              (bottom is measured from node's bottom edge;
               next node top is node-gap below, its pill center is pill-half further)
