 * the exact width from navigator.windowControlsOverlay
 * (use-window-controls-overlay-width.ts) and uses this value only when the WCO
 * API is unavailable.
 *
 * macOS uses traffic lights positioned via trafficLightPosition, not a WCO
 * overlay, so it reserves nothing here. Every other desktop platform now paints
 * the Electron overlay (Windows, WSLg, and plain Linux KDE/GNOME), so they all
 * reserve the fallback width.
