**Defining the Game's Structure** I'm solidifying the foundation for this Snake game project. Currently, I'm focusing on the single-file structure, ensuring everything resides within `index.html`. My main priorities right now are the core mechanics: arrow key controls, a growing tail, food generation, score tracking, a proper game-over sequence, and the all-important restart function. The constraints guide the decisions. **Outlining Implementation Details** Now, I'm diving deeper into the specifics. I'm visualizing the HTML structure, focusing on a `<canvas>` for the game and containers for UI elements. My CSS plan centers the canvas and adds a dark background. On the Javascript front, I'm setting up configuration variables for things like grid size, and variables for snake and food positioning, velocity, and score.

EVALUATION
Game is stuck permanently on 'GAME OVER' screen with no snake ever rendered; no input changes anything.

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.
