 * Whether an aircraft is already selected is deliberately irrelevant: an
 * explicit Cockpit action still reveals the context that supports that track.

 * @param {object} input Action outcome and coordination state.

 * @param {boolean} input.explicitUserAction Whether the user directly requested it.

 * @param {boolean} [input.restoring=false] Whether saved/session state is being restored.
 * @returns {boolean} Whether Global Context should be expanded.
