What changed

• The legacy global script was replaced with a module-based TypeScript implementation.
• Game state now lives in a single GameState object.
• Input, update, render, and audio are separated in the runtime.
• The loop now uses requestAnimationFrame instead of setInterval.
• DOM controls now provide restart, mute, and live status without relying on keyboard-only overlays.
• The UI now includes pause, difficulty, and volume controls backed by typed game settings.
• Settings and the top five local high scores now persist in browser storage.
• The runtime is split across src/game/ modules for state, input, audio, assets, update, render, and UI copy.
• The update system now has lightweight automated coverage.
• Existing image and sound assets are served from public/.
