Prompt for this run

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've implemented a playable 2048 game in a single `index.html` file with inline CSS and JavaScript. Here's what I checked: - **Initial state**: The game starts with two tiles (2s) on the board and score 0 - verified. - **Arrow key movement**: Tested left, right, up, and down movements. Tiles slide correctly and merge as expected (e.g., two 2s merge into a 4, increasing score by 4). - **Tile spawning**: After a valid move, a new tile (2 or 4) appears in an empty cell - verified. - **Score updates**: Score correctly increases by the value of merged tiles (e.g., merging two 2s adds 4 to score). - **Win condition**: The game shows "You Win!" when reaching 2048 - verified through DOM inspection. - **Game over**: When no valid moves remain, "Game Over!" message appears - verified. - **New Game button**: Resets the board and score to initial state - verified. The only remaining unverified behavior is the visual animation of tile movement and merging, which is handled by CSS transitions but cannot be fully verified in the current environment. However, the code includes proper animation classes that are applied and removed with timing, which should provide the expected visual feedback. All required functionality is implemented and working as specified. The game behaves correctly according to 2048 rules, with proper merging, scoring, and game state management.
