Future prediction clouds

Purpose: shows how the complete statistical-orbit prediction cloud develops from the current reference time to two days ahead. Display: teal points are individual orbit variants, the black cross is the nominal direction, and the empirical gold 50%, blue 90%, and red 95% contours follow the actual cloud shape. Read: a compact cloud is easier to recover; a long or split cloud calls for a wider search. The scale stays fixed for the selected object throughout playback. Required exact keyframes are supplemented only where radius, shape, or orientation changes strongly; the browser interpolates between retained exact frames.
