1//! Tray popover: Escape closes the window.
2//!
3//! On macOS the popover is an undecorated `NSPanel` + `WKWebView`. The webview often never
4//! becomes first responder, so JS `keydown` never runs. `NSEvent` local monitoring runs on the
5//! main thread for the active app only (not a system-wide global shortcut).
