// NoSignal popup overlay: one full-screen layer per screen that hosts the active
// floating panel (driven by NsShell.open). A transparent click-catcher behind the
// panel closes on outside-click; Escape also closes. Panels are positioned below
// the bar, anchored center / right / under-trigger per their `anchorMode`.
