/*
  Veyra - the log-in page.
  ==========================================================================

  Self-contained on purpose. It reads the design tokens from veyra-core.css
  and owns everything else, so the page cannot be changed by accident from
  somewhere it does not import: this is the one screen where a broken layout
  means nobody can get in.

  Always dark. The application has a light theme and the marketing site has a
  paper section, but the door into Veyra is the navy one - so nothing here
  waits on a stored theme, and there is no first-paint flash.
