SKILL.md
This skill is the shared mental model referenced by all pixijs-scene-* leaves. It explains what the scene graph is in PixiJS v8, how a Container differs from a leaf, and where each concept lives. It does not go deep on any single API; it frames the pieces and points to the skill or reference file that does.
Quick Start
const world = new Container({ isRenderGroup: true });
app.stage.addChild(world);
const hero = new Container({ label: "hero" });
hero.addChild(new Sprite(bodyTexture));
hero.addChild(new Sprite(faceTexture));
world.addChild(hero);
const mask = new Graphics().rect(0, 0, 800, 600).fill(0xffffff);
world.mask = mask;
world.addChild(mask);
hero.position.set(world.width / 2, world.height / 2);
