Prompt for this run

Build a playable Snake game on a canvas with a 20 by 20 cell board. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Use arrow keys to turn a snake that advances one cell at a time. Ignore a direction that would immediately reverse into its own neck, including rapid inputs before the next movement step. - Place one food item in an unoccupied cell. Eating it grows the snake by one segment, increases the score, and spawns new food in another unoccupied cell. - Use solid board boundaries: hitting a wall or the snake's body ends the game. Moving into a tail cell that vacates on that same non-growing step is allowed. - Provide Start, Pause/Resume, and Restart. Restart resets snake length, direction, score, food, and game state. Filling the board shows a win state instead of trying to place impossible food. - Display the controls and score. Prevent arrow keys from scrolling the page. Verify: Start the game and make a few turns to check grid-aligned movement and direction response. Pause and resume, then use Restart and check that snake length and score return to their initial values and food occupies a free cell.

I've created the necessary directories and a basic index.html file. Now, I'll create the Snake game using HTML, CSS, and JavaScript. I'll write the code directly into the index.html file, following the given requirements. Let's start with the HTML structure and basic CSS.
