Build a playable 2048 game with arrow-key tile sliding and merging, smooth animations, a score, and win and lose states.

**Developing Interactive 2048** I'm focusing on implementing the core game mechanics for 2048. This includes handling arrow-key input for tile movement and merging, and ensuring a smooth user experience with CSS transitions for animations. Tracking the score and defining win/loss conditions are also high on my agenda. **Structuring Game Elements** I'm now focused on building the foundational HTML for the game. This involves setting up the main container, the 4x4 grid structure, and placeholders for displaying the score and win/loss messages. My next step will be to define the CSS for styling these elements and the tiles themselves.

**Reviewing Core HTML** I'm currently examining the `index.html` file. My focus is on ensuring the 2048 game implementation is entirely self-contained within this single page, as per the requirements, with CSS and JavaScript embedded directly.
The 2048 game has been successfully built as a single-page, self-contained application in `index.html`. ### Features Included: - **Responsive Logic:** Handles sliding and merging of tiles in all four directions using arrow keys. - **Smooth Animations:** Uses CSS transitions for tile movement and keyframe animations for tile appearances and merges. - **Score Tracking:** Real-time score updates as you merge tiles. - **Win/Loss States:** Detects when you reach the 2048 tile or when no moves remain. - **Modern UI:** Matches the classic 2048 aesthetic with a clean color palette and clear typography. ### How to Play: 1. Open `index.html` in any modern web browser. 2. Use the **Arrow Keys** to move tiles. 3. Merge matching numbers to reach **2048**! 4. Use the **New Game** button to restart at any time. The file is located at `/workspace/index.html`.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
2048 clone responds to arrow keys with tile movement and merging and score updates; click/drag/wheel/enter/space have no effect as expected.

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.
