Build a playable 2048 game using HTML elements and CSS with a 4 by 4 board. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Arrow keys slide tiles toward the selected edge. Adjacent equal tiles merge once per tile per move, and the score increases by the value of each new merged tile. - For example, moving [2, 2, 2, 2] left produces [4, 4, 0, 0], not [8, 0, 0, 0]. Moving [2, 2, 4, 0] left produces [4, 4, 0, 0]. These examples describe the move before spawning a new tile. - Start with two tiles. After a move that changes the board, spawn exactly one tile in an empty cell: 2 with 90% probability, otherwise 4. Do not spawn after an unchanged move. - Animate movement and merging without allowing rapid input to corrupt board state. Prevent arrow keys from scrolling the page. - Show score, a win message on reaching 2048, and Game Over only when no valid move remains. Provide New Game to reset board and score; allow continuing after a win. Verify: Play a short sequence of arrow-key moves and check that tiles slide, a valid move adds a tile, and any observed merge updates the score by its merged value. Use New Game and check that the board returns to two tiles with a reset score.

I need to build a complete 2048 game in a single self-contained HTML file. Let me think through the requirements: 1. **4x4 board** with HTML elements and CSS 2. **Arrow keys** slide tiles toward the selected edge 3. **Merging logic**: Adjacent equal tiles merge once per tile per move (e.g., [2,2,2,2] left → [4,4,0,0]) 4. **Score updates** by the value of each new merged tile 5. **Start with two tiles** 6. **After a move that changes the board**: spawn exactly one tile (90% chance of 2, 10% chance of 4) 7. **Don't spawn after an unchanged move** 8. **Animate movement and merging** without allowing rapid input to corrupt state 9. **Prevent arrow keys from scrolling** 10. **Score display** 11. **Win message** on reaching 2048 (with continue option) 12. **Game Over** when no valid move remains 13. **New Game** button to reset Let me write a complete, self-contained HTML file with inline CSS and JavaScript.

Now let me run the browser to test the game and verify the behavior.

Let me read the file to understand the current implementation and check if it meets all the requirements.
