/* ==========================================================================
   IRONITT v2 — dialogs
   --------------------------------------------------------------------------
   The shared modal (.modal-overlay > .modal), the confirm dialog, the scrim
   behind side panels, and the three buttons and the form row every dialog
   uses. A dialog floats, so it is the one surface here that carries a shadow.

   App.closeModal() tears the overlay down on the overlay's own animationend,
   so the scrim and the surface share one clock (--surface-glide, 250ms).
