1// nx_viz_icicle.nx -- COMPOSED live ICICLE: parse a tree TSV (parent/value/label), partition it with
2// nx_viz_partition (subtree-proportional spans), and draw each node as a depth-banded rectangle (x from its span,
3// y from its depth) coloured by tier (nx_viz_color), labelled via nx_viz_shape's serializer. Self-contained HTML
