pragma ComponentBehavior: Bound

// NoSignal slim top bar (interface redesign 2026-06-14).
// Flat 38px translucent-glass PanelWindow at the top edge. Three zones:
//   left  : logo · | · workspaces · | · window-title
//   center: clock
//   right : media · bell · wifi · bt · volume · battery · | · power
// Each interactive module is a BarPill (hover bg; active = accent.soft + accent
// fg). `openPanel` is the single shell-level "one panel open at a time" string;
// clicking a pill toggles it. The popup panels themselves are built next — for
// now a click just highlights the pill. Reuses the existing service singletons.
