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 a playable Snake game in a single HTML file. Let me create a complete Snake game with:
1. Canvas-based rendering
2. Arrow key controls
3. Growing tail when eating food
4. Food spawning
5. Score display
6. Game over state
7. Restart functionality

I'll write this as a single self-contained HTML file with CSS and JavaScript inline.
write /tmp/ws/index.html (10660 bytes)

The file has been created. Let me verify its contents briefly to ensure everything is in order.

Done! I've created a complete Snake game in `/tmp/ws/index.html`. Here's what's included: **Features:** - 🕹️ **Arrow key controls** - Use Up/Down/Left/Right to steer the snake - 🍎 **Food system** - Red food pellets spawn randomly; eating them grows the tail - 📈 **Score tracking** - +10 points per food eaten, displayed at the top - 💀 **Game over** - Triggered by hitting walls or your own tail - 🔄 **Restart** - "Play Again" button appears on game over **Visual Design:** - Dark gradient background with grid lines - Glowing green snake with gradient shading and cute eyes on the head - Pulsing red food with highlight effect - Smooth animations and hover effects on the restart button Open `index.html` in any browser to play!

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.
