/* Shared chrome for the transactional pages on dash.oaica.com — the checkout, the
   success page, the terms and the privacy notice. The marketing pages live on
   oaica.com; these keep the same top bar, the same tokens and the same type so a
   buyer crossing between the two sites does not feel handed off.

   Deliberately a plain stylesheet and not a framework: these pages carry no build
   step, and the whole visual vocabulary is a handful of tokens plus one bar. */
