/* Blue Sky Consulting — shared styles
   Direction: an engineering advisory firm's site, set like a technical publication.
   Serif display (Newsreader) for voice, a quiet grotesk (Schibsted Grotesk) for reading and UI.
   Palette: white, navy, cool greys. The red-to-blue horizon appears only in the logo,
   the top signature line and the hero diagram. */
