/* ===========================================================================
   dist-explorer.css -- styling for the two interactive panels in chapter 07.

   Loaded after notes.css (see the css: list in _quarto.yml) and scoped
   entirely under .dx, so it cannot reach the rest of the book. The palette is
   the same UW purple / lilac / grey used by the ggplot figures, so an
   explorer sitting between two static figures does not look imported.

   Nothing here is needed by the PDF build; the LaTeX format never loads css.
