- Add missing <script src="js/tutorial.js"> to index.html (before main.js)
- startTutorial() was called but undefined → ReferenceError on every new game
- Remove game.js (3288 lines of dead code, not loaded by any script)
- Update smoke test to not require game.js
Ref: QA report #85 (BUG-07 category — missing script references)
