The book and the HTML gain "Setting up your environment" after the guide

chapters lists setup.typ second and #doc takes a setup id. Shell lines
(#cmd) follow the density too: roomy in the book and the HTML, with a
tint and space around them, tight on the A4 sheet; the book sets code
blocks on the same tint.
