// NoSignal shell-level popup state. "One panel open at a time" — `open` is the
// id of the active panel ("" = none). `anchorX` is the scene x of the trigger
// (a bar pill) center, used to position under-trigger / right-anchored popups.
// `screen` is the name of the output that owns the open panel, so a per-screen
// NsOverlay shows it on ONLY that monitor instead of mirroring on all of them
// (multi-monitor fix, 2026-06-20). "" = no owner → show on all screens (used by
// the full-screen power modal opened from a global keybind, which has no screen).
// The NsBar pills call toggle() with their screen; NsOverlay matches on `screen`.
