// How one entity's landed impacts look and feel: the hull reaction at the drawn impact point, and the player's camera
// kick. The simulation publishes each impact once on the entity's Capabilities (FireControl); Feedback.Cue decides how
// hard it reads and whether the camera feels it, DrawAhead.Carried decides where it is drawn; this decides nothing.
// The hull effect is drawn only where the player's instruments place the ship (ActionGameManager.DrawsAt).
// The shield ripple is ShieldManager's. Everything here is display-only and runs in real time.
