On Wayland it goes through libei + xdg-desktop-portal, which injects to the compositor's input focus — Wayland's security model has no per-window background targeting, so a specific non-focused window cannot be aimed at; when no libei backend is available the tool returns a structured background_unavailable error. 'foreground' is the explicit escalation: activate the target (X11 _NET_ACTIVE_WINDOW; Wayland compositor activate), inject, then restore the prior active window — a brief focus swap unless the target was already active. Matches the macOS / Windows delivery_mode surface.",
