/**
 * Wrapper around PixiJS's official Assets API.
 *
 * Pixi handles caching, format detection (WebP/AVIF/PNG), and bundle loading
 * out of the box — we just expose a small surface for the typical game flow:
 *
 *   await assets.loadBundle({ player: 'sprites/player.png' });
 *   const tex = assets.get('player');
 *
 * For larger projects, switch to manifest-based bundles
 *   (assets.initManifest(manifest)) so background-load-by-bundle becomes
 *   one call.
