   Split card: a photo panel on the left (images/portal/login-side.jpg, a crop
   of the site's own Uploads/VisionImage/vision.jpg) with the portal's promise
   over a dark indigo fade, and the form on the right - brand, heading,
   subtitle, one underlined field, a full-width button, the copyright line.
   Colours follow the portal (portal-ui.css): indigo on a lavender ground.
