// Custom-themed polkit authentication agent, replacing hyprpolkitagent's
// default (unthemed, light) dialog. PolkitAgent/AuthFlow handle the actual
// D-Bus/PAM plumbing internally — this file is purely the UI around it.
//
// Rendered as a slim layer-shell bar anchored to the top-center of the
// screen (like mako's notification popups) rather than a normal toplevel
// window — this sidesteps Hyprland window placement entirely, so there's
// no need for float/center window rules.
