/* ==========================================================================
   IRONITT v2 — call surfaces
   --------------------------------------------------------------------------
   The incoming-call window (#notif-call-modal, js/island.js _showCallModal)
   and the small badge that stays on screen during a call or a screen share
   (#notif-badge, _showBadge). Both float, so both carry a shadow; neither
   glows or pulses. The window is about one decision, so its two buttons
   say what they do.
