Build a playable Snake game on a canvas with arrow-key controls, a growing tail, food, score, and a game-over and restart state.

We need to produce a single index.html with a playable Snake game. Must include canvas, arrow-key controls, growing tail, food, score, game-over and restart. Use no external resources. Provide HTML with style and script. We'll write the file.

We have written the file. Need to confirm it's correct. Provide final answer.

The file **`index.html`** has been created in the current directory with a complete, self‑contained Snake game: - Canvas rendering with a 20×20 grid - Arrow‑key controls (up/down/left/right) - Growing tail when food is eaten - Score and persistent high‑score (saved in `localStorage`) - Game‑over overlay and a **Restart** button (also press **Space** to restart) - All CSS and JavaScript are inline; no external resources are used. You can open `index.html` in any browser to play. Enjoy!

TAKE IT TO CODE

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.
