I've created a complete, self-contained 2048 game in a single HTML file. The implementation includes: 1. **Arrow key controls** for moving tiles 2. **Touch swipe support** for mobile devices 3. **Smooth animations** for tile movement and merging 4. **Score tracking** with local storage for best score 5. **Win condition** (reaching 2048) 6. **Game over detection** when no moves remain 7. **Responsive design** that works on different screen sizes 8. **Visual feedback** with color-coded tiles and merge animations The game is fully playable with all requested features. You can: - Use arrow keys to move tiles - Swipe on touch devices - See your current score and best score - Get "You Win!" when reaching 2048 - Get "Game Over!" when no moves remain - Restart at any time with the New Game button The implementation uses only vanilla JavaScript, CSS, and HTML with no external dependencies. All styles and logic are contained in a single file as requested. To play the game, simply open the `index.html` file in any modern web browser.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
