Pixijs Scene Core Concepts

If you're working with PixiJS v8's scene graph, this is your mental map. It explains the critical Container versus leaf distinction (leaves like Sprite, Graphics, and Text must not have children anymore), how transforms compose from local to world space, and where concepts like render groups, culling, masking, and z-ordering fit together. The real value is that it frames the whole system and points you to the right specialized skill for each display object type. Think of it as the shared context for all the pixijs-scene-* skills. One heads up: v8's strict separation between grouping nodes and drawing nodes is a breaking change from earlier versions, so if you're migrating code that added children to sprites, this will save you debugging time.
