/* WATI support widget (js/wati-chat.js). The vendor stylesheet paints its button, CTA bubble and
   chat panel at `z-index: 16000160 !important`, which would float all three over every overlay this
   app has -- the bubble lands bottom-right, exactly where a dialog's Save/Cancel buttons sit, and it
   would even cover the session-expiry prompt. Giving the widget's root a stacking context of its own
   confines those !important values inside it, so the whole widget layers as a single element at 30:
   above page content, below the menus (40/50), modals (60/61), select panels (120/121) and the
   session dialog (1000/1001). `position: relative` does not disturb the fixed positioning of the
   children -- only transform/filter/contain would. */
