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

The user wants me to build a Snake game as a single-page web app in one self-contained index.html file. Let me create this with: 1. Canvas for rendering the game 2. Arrow key controls for movement 3. Snake that grows when eating food 4. Food spawning randomly 5. Score tracking 6. Game-over state when snake hits wall or itself 7. Restart functionality I'll write all CSS and JavaScript inline within the HTML file.

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.
