/* Public site (site/, D-058): home pages, guides and their hub. Same tokens as app.css (colours and type of the
   original mock-up), light and dark through html[data-theme]. The design is the home page of D-057: editorial and
   quiet, type carries the page, hairlines instead of boxes, colour only where it means something and the brand accent
   for small signals; the main button is ink on paper in both themes. Classes are "s-" (site chrome, guides) and
   "lp-" (home page components); the app's stylesheet, loaded when the home page opens an app screen, uses neither. */
