   Tokens lifted verbatim from the app's own public/style.css so the site and
   the product are visibly the same object. Do not invent new colours here;
   compose with these.

   Dark is the marketing default (the product's "Night Studio" direction), but
   both themes are complete and the toggle works in both directions.
