/* ===========================================================================
   The Texas Water cat.

   A character a twelve-year-old designed, and a site that follows her from the
   rain down to somebody's kitchen tap. The whole page is one descent: it starts
   in a dark abyss and surfaces into a bright kitchen, so the palette does the
   narrating and the copy can stay short.

   Everything here is honest about the water. The facts are the utilities' own
   published ones; nothing is rated, scored or graded by us.
