/* Design History Museum, shared theme.
   Tokens and type for index.html, eras.html and book.html, drawn from Rohan
   Kartik's portfolio system (page palette, Sharpener colour ramps, golden
   ratio type). Every page links this file with a relative path, so the site
   still opens straight off the disk.

   Fonts: pf-marlet-display and urw-form are Typekit faces locked to the
   portfolio domain, so they are named first only for machines that have them
   installed. Playfair Display (700, the only weight Marlet ships) and DM Sans
   are what actually renders. Noto Sans Bengali covers local-language names.
   Offline, the stacks fall through to system faces. */
