Covers the bread and butter of PixiJS v8 scene graphs: how Container holds children, applies transforms, and manages rendering order. You'll reach for this whenever you're grouping sprites, building composite objects, or setting up hierarchies. The constructor options rundown is handy (isRenderGroup, sortableChildren, boundsArea), and the zIndex sorting explanation clears up a common point of confusion. Good coverage of addChild variants, transform properties, and the pivot versus origin distinction. If you're doing any nontrivial PixiJS work, you're using containers constantly, so having the API and patterns documented in one place saves digging through docs.
