The signature SHAP summary: one jittered point per (observation, variable),
positioned by SHAP value and colored by the feature value, min-max scaled
to [0, 1] within each variable so every variable's own range maps
to the full color gradient. Categorical features have no numeric value and
render as a neutral gray (no numeric value to scale).
