   Custom V3 modal + toast styles — pairs with /v2/js/v3-modal.js
   and /v2/js/v3-toast.js to replace Bootstrap modal + bootbox +
   bootstrap-notify.

   Shared across search-v2, mydomains, app, ... — page-specific
   skins (className passed via show()) layer on top.

     V3Toast container   : 2147483641
     Kit overlay (XWK)   : 2147483647  (always wins)
