   Era Books (exodusnds.com/era-books/<era>)

   Shared structure for every Era Book section: page frame, header, landing
   page, chapter page with its chapter list and "On this page" list, pager,
   footer. It carries no look of its own beyond neutral defaults. Each era's
   theme.css, loaded after this file from assets/era-books/<era>/, sets the
   --eb-* tokens and styles the book's own boxes (bounty, instrument, ...).
   Classes are eb-*; tokens are --eb-*.
