/* ---------------------------------------------------------------------------
   app.subulate.com — account screens.

   Same palette, type and button shape as the marketing site, so signup does not
   feel like a different product. Deliberately its own file rather than a link
   to subulate.com's stylesheet: a cross-origin CSS dependency means an outage
   or a cache mistake on the marketing site would strip the styling off the
   signup form, which is exactly the failure that already bit this project once.
