/* =========================================================================
   The Normal Curve and z-Scores — tool-specific styling
   -------------------------------------------------------------------------
   Shared page furniture comes from components/tool-kit.css. What is specific
   here is the density curve, the shaded area below the chosen score, the
   standard-deviation band and the two-curve comparison.

   The shaded area carries a diagonal hatch as well as a fill, the score is a
   labelled rule, and the second curve is dashed and named at its peak, so no
   distinction depends on colour.
