/* ==========================================================================
   Scoutnet CRM - sign-in pages (layout Shared/AdminLTE/_Auth.cshtml)
   --------------------------------------------------------------------------
   Split screen: an illustrated brand panel (animated SVG, soft moving mesh) and
   a glass card with the form. Below 992px the panel becomes a compact band above
   the card; inside a cross-origin iframe (ViciDial, html.embedded-frame) and on
   short screens it shrinks further so the form fits a ~400x600 frame.
   Motion uses transform / opacity (plus one-off SVG stroke draws) and is switched
   off entirely for prefers-reduced-motion. Builds on the theme-modern tokens.
