The Snake game is complete at `/tmp/ws/index.html`. Here's what's included: **Gameplay:** - Arrow-key controls to move the snake - Snake grows when eating red food - Score tracking (current + best, persisted in localStorage) - Game over on wall or self-collision - Restart by pressing any arrow key after game over **Visuals:** - Dark theme with green snake and red food - Snake has gradient coloring (brighter head, darker tail) - Eyes on the snake head that follow direction - Glowing effects on snake head and food - Subtle grid lines - Animated "Press any arrow key to start" text - Game over overlay showing final score **Technical:** - Single self-contained HTML file - No external dependencies - Canvas-based rendering - `requestAnimationFrame` game loop with fixed tick rate (110ms) - 20×20 grid on 400×400 canvas

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.
