/*
 * RetaDesk admin panel layout (docs/admin-panel/implementation_plan.md).
 * Built on the new design's stylesheet (/ui/rd.css: Bootstrap 5.3.8, AdminLTE 4 components, --rd-* tokens).
 * The top bar is slate, not RetaDesk Red, so an operator always sees that this is the platform panel and not a
 * client's RetaDesk. Chrome 109 floor: no color-mix(), no CSS nesting.
