**Generating Self-Contained HTML**

I'm focusing on creating a single HTML file to encapsulate the Snake game. This involves embedding all necessary CSS within `<style>` tags and JavaScript logic inside `<script>` tags, ensuring no external dependencies are required.

**Embedding Game Elements**

I'm actively integrating the game's styling and logic directly into the HTML. This means all CSS rules are now within `<style>` tags, and the JavaScript functions for movement, scoring, and game over are embedded within `<script>` tags.

**Structuring HTML Foundation**

I am currently laying the groundwork for the self-contained HTML file. This involves creating the basic structure with the `<!DOCTYPE html>`, `<html>`, `<head>`, and `<body>` tags, including the essential `<canvas>` element and placeholders for internal `<style>` and `<script>` blocks.

**Implementing Game Logic**

I am now integrating the core game mechanics. This involves writing the JavaScript functions for snake movement, food generation, collision detection, scoring, and the game loop itself, all to be self-contained within the HTML.

**Constructing Canvas Structure**

I am currently building the foundational HTML for the self-contained Snake game. This involves establishing the `<!DOCTYPE html>`, `<html>`, `<head>`, and `<body>` tags, and crucially, embedding the `<canvas>` element along with placeholders for internal `<style>` and `<script>` blocks.

**Finalizing Self-Contained Code**

I've successfully embedded all JavaScript logic and CSS styling directly within the HTML document. The game is now fully self-contained, requiring no external files or links, and is ready for deployment.

**Finalizing Self-Contained Code**

I've successfully embedded all JavaScript logic and CSS styling directly within the HTML document. The game is now fully self-contained, requiring no external files or links, and is ready for deployment.

**Updating Game Logic**

I've refined the game loop to handle snake movement, collision detection with walls and itself, and food consumption. The snake now grows when it eats, and its tail is removed otherwise. I am also generating new food positions after consumption.

**Refining Canvas Drawing**

I am now focusing on the visual rendering aspects. This includes defining clear functions for drawing the snake, the food, and the game background onto the canvas, ensuring smooth and consistent visuals.

**Enhancing Game Loop**

My current focus is on refining the core game loop. I'm optimizing the update mechanism to efficiently handle snake movement, food generation, and collision detection, ensuring a responsive and engaging gameplay experience.

**Integrating Game Elements**

I'm actively integrating all necessary game components. This involves embedding the CSS for styling and the JavaScript logic for gameplay directly within the HTML, creating a completely self-contained experience.

**Structuring HTML Foundation**

**Updating Game Logic**

I'm refining the game loop, ensuring smooth snake movement, accurate collision detection with walls and itself, and proper food consumption leading to growth. New food positions are generated dynamically after each successful meal, and the score updates accordingly.

**Refining Canvas Drawing**

My current focus is on the visual rendering. I'm implementing clear and efficient functions to draw the snake segments, the food item, and the game's background onto the canvas, aiming for crisp and consistent visuals.

**Enhancing Game Loop**

I am now optimizing the core game loop. This involves fine-tuning the update mechanism for responsive snake movement, dynamic food generation, and robust collision detection, all contributing to a fluid gameplay experience.

**Integrating Game Elements**

I'm actively embedding all required game components. This entails incorporating the necessary CSS for styling and the JavaScript logic for gameplay directly within the HTML, thereby creating a fully self-contained application.

**Structuring HTML Foundation**

I'm establishing the fundamental structure for the self-contained HTML file. This includes the doctype, html, head, and body tags, incorporating the essential canvas element and setting up placeholders for internal style and script blocks.
