   Public marketing site and authentication.

   Shares the product's tokens deliberately: the website and the signed-in
   application should read as one company, not two. Anything specific to the
   marketing pages lives here; the tokens themselves are defined once in
   app.css and re-declared below so a public page never depends on loading
   the application stylesheet.
