   Tool, Not Author — companion site
   Design thesis: the AUTHOR speaks in warm serif; the TOOL
   speaks in cool monospace. Author voice = EB Garamond on warm
   paper. Tool output (stamps, changelog, prompts, audit) = IBM
   Plex Mono on a cooler panel. The page renders the book's
   argument in type and temperature.
