/* The documentation (crates/tally-web/src/docs), over tokens.css, app.css and guides.css
   (the masthead, the breadcrumbs and the colophon). The landing's manual look, made for
   reading and coming back to: the menu in a column on the left, numbered sections with
   mono labels and hairlines, the page's contents on the right, code on ink panels.
   The walkthrough's steps are marked with the tally itself, one stroke a step; the fifth,
   across, is the receipt at the end. Every class here is docs-…, so neither the app's nor
   the other pages' rules reach in (tally-web's stylesheets test checks). No inline style:
   tabs switch with radio buttons and :has(), and the script only adds conveniences. */
