Problem\nWhen lazy-loaded chunks (Three.js, Scene3D, PixelRunner) are loading, the screen shows nothing — Suspense fallback is null. This makes the app feel unresponsive.\n\nSolution\nCreate a LoadingScreen component (src/components/LoadingScreen.tsx) with:\n- Animated pixel-art spinner (CSS-only, no extra deps)\n- 'LOADING...' text in JetBrains Mono\n- Dark background matching game theme\n- Optional: loading tips that cycle every 3s\n\nReplace fallback={null} with fallback={<LoadingScreen />} in all <Suspense> boundaries in Game.tsx.
