/* AI adoption case study (DevToDollars), version 3: a full page website.
   Every band runs edge to edge. The hero fits one screen and gives the product screens most of
   it. Facts carry the story as numbers, icon charts, flows and the client's own illustration
   style; running text stays short. Display type in Montserrat (the DevToDollars wordmark face),
   body in the site's system stack, colour from the client's palette: indigo, gold, slate, white,
   plus tints and shades of the indigo.
   Every selector is scoped to .ai-cs so the page drops into devtodollars.com unchanged. */
