// - Routes are requested given a chord (key + modifiers) and a routing policy.
// - Routes are resolved during NewFrame(): if keyboard modifiers are matching current ones: SetKeyOwner() is called + route is granted for the frame.
// - One route may be granted to a single owner. When multiple requests are made we have policies to select the winning route (e.g. deep most window).
