/* Autocode's marketing stylesheet. Plain CSS, no build step.
   The page is two grounds: night (the hero and the closing line) and paper
   (how it works). The accent is the only colour on either; the mono face is
   for the things a product would print — names, times, step numbers.
   The block from here to the first rule is generated with the logo (brand
   colours and faces); change them together. */
