Detailed Description

Per-element typed state keyed by ID, kept across frames (drag start, double-click timing).

Get, GetOrCreate and Touch keep an entry alive; EndFrame evicts the rest. GUIStateManager touches the IDs in a live interaction (capture, focus, drag, active), so their state survives frames without events. Types up to 64 bytes are stored inline.
