description	Use this skill first for ANY PixiJS v8 task; it routes to the right specialized skill for the job. Covers the full PixiJS surface: Application setup, the scene graph (Container, Sprite, Graphics, Text, Mesh, ParticleContainer, DOMContainer, GifSprite), rendering (WebGL/WebGPU/Canvas, render loop, custom shaders, filters, blend modes), assets, events, color, math, ticker, accessibility, performance, environments, migration from v7, and project scaffolding. Triggers on: pixi, pixi.js, pixijs, PixiJS, v8, Application, app.init, Sprite, Container, Graphics, Text, Mesh, ParticleContainer, DOMContainer, GifSprite, Assets, Ticker, renderer, WebGL, WebGPU, scene graph, filter, shader, blend mode, texture, BitmapText, create-pixi, how do I draw, how do I render, how do I animate in pixi.

Entry point for the PixiJS v8 skill collection. PixiJS is the fastest library available for the web, working across all devices and allowing you to create rich, interactive graphics and cross-platform applications using WebGL, WebGPU, and Canvas as a fallback.

snapmatch integration (read before mounting Pixi inside a component)

PixiJS is first-party in snapmatch at pixi.js@^8.18.1 for any canvas-based UI. It is a side channel the same way anime.js is — render functions stay pure; everything that touches Pixi (new Application(), Ticker.add(...), sprite mutation, scene-graph reads) lives inside useEffect / useLayoutEffect / event handlers, never during render.

The canonical lifecycle wrapper is usePixiApp(canvasRef, setup, deps) in apps/<name>/app/canvas/use-pixi-app.ts:

• Owns async Application.init({ canvas, resizeTo, preference: "webgl", autoStart: options.autoStart ?? !reducedMotion }).
• Calls the user setup(app, { reducedMotion }) callback once init resolves; the callback registers children and Ticker tasks and may return a cleanup function.
• Tears down on unmount via app.destroy(true, { children: true, texture: true }), with cancellation that survives StrictMode double-mount.
• Detects prefers-reduced-motion: reduce once at mount and passes it to setup; callers must skip Ticker registration when true (static frames still render).
• Static scenes that only update on resize or pointer input should pass autoStart: false and call app.render() from those handlers.
• React owns the <canvas> DOM node; Pixi only paints into it. The wrapping component renders <canvas ref={canvasRef}> inside a sized container.

Pillar mapping (same constraints as the rest of the stack):

• Pillar 1 (Storybook-first) — every Pixi-wrapping component ships with a sibling *.stories.tsx and a Playwright story spec.
• Pillar 2 (Zod-first types) — Pixi-wrapping component props are still z.object schemas wrapped by defineComponent. Pixi-internal types (Texture, Container, etc.) are runtime-only and don't need Zod validation.
• Pillar 3 (remote-first, locally resilient state) — Pixi DisplayObjects never own durable data and Pixi code never calls Firestore or IDB. Generated progress/settings remain IDB-local. Shared state is implemented as Firestore snapshot → Zod → IDB replica → Jotai; local commands return through the durable IDB outbox and exact receipt reconciliation. Pixi receives only React-managed refs derived from Jotai. Browser-session Anonymous Auth is implemented, production domain sync is disabled, and App Check is not implemented.
• Pillar 4 (CLI-gate-first) — Pixi component story specs run in the Playwright storybook project under headless Chromium. WebGL via SwiftShader is reliable; the default preference: "webgl" in usePixiApp keeps tests deterministic.

Seed example: apps/example-game/app/components/pixi-canvas-demo/ (and the same in the generator template) — a rotating square that demonstrates Ticker registration, reduced-motion short-circuit, and the canvas-ref-as-Pixi-canvas pattern.
