I'll create a complete, single-file 2048 game with arrow-key controls, smooth animations, score tracking, win/lose states, and a clean UI — all in `index.html` in the current directory.

The 2048 game is built and saved to `index.html`. Just open it in any modern browser to play. **Features:** - **Arrow-key controls** (← ↑ → ↓) for tile sliding and merging - **Smooth CSS animations** for tile movement, merging, and new tile appearance - **Score tracking** with localStorage-persistent best score - **Win state**: displays when you create a 2048 tile (can keep playing) - **Lose state**: displays when no moves remain - **Touch/swipe support** for mobile devices - **Responsive UI** with clean gradient styling and a glass-like grid container

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.

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.
