Class: InteractionSystem

Renderer pointer events → per-entity emitters with ancestor bubbling.

Mirrors InteractionComponent / BlockInputComponent add+remove onto SetNodeInteractive so the renderer hit-tests the right nodes. BlockInputComponent additionally pushes an explicit hit area derived from UITransform — that's how an empty container becomes a tap blocker.

Bubbles through the ancestor chain; stopPropagation() and the swallow flags terminate it. Cursor changes apply on enter, restore on leave.
