The file has been written. Let me verify it exists and looks correct.
The file is ready. Here's what the **Snake** game includes: ### Features - **Canvas-based rendering** with a 30×30 grid and 20px cells - **Arrow-key controls** — up / down / left / right - **Growing tail** — the snake extends by one segment each time food is eaten, with no tail removal - **Food** — pulsing red orb with a glow effect and a shiny highlight - **Score** — displayed top-left; +10 per food eaten - **High score** — persisted in `localStorage` and shown top-right - **Game-over state** — death on wall or self-collision; overlay shows score and "Press any arrow key to restart" - **Start screen** — initial overlay with instructions - **Particle effects** — burst of colorful particles when food is eaten - **Snake eyes** — the head has animated eyes that follow the movement direction - **Fully self-contained** — no external resources, CDNs, or network requests Open `index.html` in any browser to play.

MEASUREMENTS
