   Nell & Key
   ============================================================================
   One quiet book. Warm ivory, forest ink, one terracotta accent used as a
   full stop and almost nowhere else. The type is the design: an expressive
   serif for titles, the same serif at reading size for prose, a plain sans
   for anything a person operates.

   Shared by the marketing page and the chapter, so the chapter looks like the
   page promised and the page looks like the chapter delivers.
