Run Conway's Game of Life on a full-screen canvas grid with click-and-drag to toggle cells, plus play/pause, step, randomize, and clear controls.

The user wants a full Conway's Game of Life implementation with:
1. Full-screen canvas grid
2. Click-and-drag to toggle cells
3. Play/pause controls
4. Step button
5. Randomize button
6. Clear button

I need to create a single self-contained HTML file with inline CSS and JavaScript. Let me plan this:

1. HTML structure with canvas and control buttons
2. CSS styling to make it full-screen and responsive
3. JavaScript for:
   - Game of Life logic (conwaysGameOfLife function)
   - Canvas rendering
   - Click-and-drag cell toggling
   - Play/pause functionality
   - Step functionality
   - Randomize functionality
   - Clear functionality
   - Animation loop

Let me create this as a single index.html file. I'll use a grid-based approach where each cell is a pixel on the canvas. The grid size will be based on the canvas dimensions.

Key considerations:
- Use requestAnimationFrame for smooth animation
- Track mouse state for drag toggling
- Implement proper Game of Life rules
- Make controls intuitive
- Ensure the canvas fills the screen and resizes appropriately

Let me write the complete index.html file.

I'll create a complete, self-contained Conway's Game of Life web app with all the requested features. Here's the implementation:

The user wants a complete Conway's Game of Life web app with specific features. Let me create a comprehensive, self-contained HTML file that includes:

1. Full-screen canvas grid
2. Click-and-drag to toggle cells
3. Play/pause functionality
4. Step button
5. Randomize button
6. Clear button
7. Speed controls
8. Generation and population counters
9. Responsive design
10. Modern UI with gradients and animations

I'll write a complete index.html file with embedded CSS and JavaScript, no external dependencies. Let me make sure it's all self-contained in one file as requested.
