Choreography Stagger

Staggered list choreography — keyed tiles enter and leave with incremental delays via OrbitalPresenceGroup.

Orbital choreography means spacing enter delays across list items so additions and removals feel sequential rather than simultaneous. Use the demo controls to switch presets (Fade, SlideBottom, Collapse) and tune stagger duration. For production lists, wrap keyed OrbitalPresenceGroupItem children inside OrbitalPresenceGroup.
