   One centred card over a quiet sunrise. Every state the page can show
   (sign-in, invitation, chooser, account, expired, no access, closed,
   unavailable, not configured) uses the same card, so the look never breaks.
   Fonts and the logo are served from this folder; nothing loads from elsewhere.
