I'm going to create a complete 2048 game implementation in a single HTML file.

I need to define the CSS custom property for the gap value that I'm using in the layout.
I need to define the `--gap` CSS variable I referenced.

Done. `index.html` is a complete, self-contained 2048 game. Features: - **Arrow keys** (or WASD) to slide/merge tiles; **swipe** on touch devices - **Smooth animations**: tiles glide via CSS transforms, new tiles pop in, merges bump - **Score** tracking with a persisted **Best** score (localStorage) - **Win state** at 2048 and **Lose state** when no moves remain, both shown via an overlay with a restart button - Responsive layout with the classic 2048 color scheme Open it directly in any browser to play — no network or external assets needed.
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 correctly to arrow keys and WASD with tile movement, merging, and score updates; no self-animation or pointer input reaction.

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.
