pub fn get_window_opacity(
state: &Arc<AppState>,
args: &Value,
) -> Result<Value, String>Expand description
Return the currently tracked opacity for a label.
Reads from HostState.window_opacities — reflects the last value applied
via set_window_opacity, not the Win32 layer. Used by the frontend to
restore opacity on window init without an extra IPC round-trip.
