/* =====================================================================
   The Book of Trades (js/discovery/discovery-book.js)
   A field book from Lamplight Crossing: an oxblood board with brass
   corners, paper pages with a spine shadow, brass thumb tabs for the
   parts, cloth tabs for a chapter's sections. Stencil for titles (the
   Crossing's lettering), Alegreya for reading, Plex Mono for addresses.
   Numbered steps and marginal notes are rust, the book's only red.
