/*
  Night Desk theme for the public auth pages (login/register and the
  email/phone verification steps chained after registration) - matches
  app/static/landing.html's palette and type system. Deliberately its
  own stylesheet rather than an addition to style.css: the rest of the
  app (dashboard, sidebar) keeps its existing light theme, and this file
  is only linked from auth_base.html, so it can't leak into any other
  page.
