/*
  Oklart Guard's pages on oklart.com, and the page for addresses that lead nowhere. The same black, white
  and grey as the front page and Oklart Mail's page (/mail/mail.css), and as the apps, in the same typeface.

  The page is a grey desk. What lies on it as a white sheet is something real: the app's own window, what the
  app says about each kind of junk, the two subscriptions. What we at Oklart never see stands in grey, as the
  o in the logo does.

  The switch between light and dark is a checkbox, so it works without script. /assets/mode.js only remembers
  the choice from one page to the next.
