+"""Bridge helpers for using the SHAP library's plotting ecosystem with
+Shapley values computed by shapiq.
+
+We use shapiq for the actual Shapley-value computation — it's faster and
+extension-friendly for TabPFN — but the SHAP library's plotting ecosystem
+(``shap.plots.waterfall``, ``beeswarm``, ``summary``, ``dependence``, etc.)
+is mature and widely used. This module bridges the two.

+The ``shap`` package is **not** part of the ``interpretability`` extra. Install
