   Local stylesheet. Depends on the site design tokens from
   ../../../css/style.css (loaded first). All tutorial styles are
   namespaced with the "dgp-" prefix to avoid leaking into the
   rest of the site. Tables reuse the global .table-wrap; the ad
   slot reuses the global .ad-wrap / .ad-slot.
