Handles PixiJS v8's ticker API for per-frame logic and render loop control. You'll use this when animating sprites, running physics updates, or managing frame timing. The main gotcha is that v8 passes the entire Ticker instance to callbacks, not a raw delta number like v7 did, so `(dt) => sprite.rotation += dt` will silently break. The guide covers deltaTime versus deltaMS versus elapsedMS (they're different units with different scaling behavior), UPDATE_PRIORITY ordering so physics can run before rendering, and frame rate capping with maxFPS and minFPS. Also explains when to use Ticker.shared versus app.ticker versus rolling your own instance, plus the onRender hook for object-specific updates.
