I'll create a single-page web app for Conway's Game of Life with all the requested features in one self-contained index.html file. Let me first check the current directory and then create the file.

Now I'll create the index.html file with Conway's Game of Life implementation:

Now I'll create the complete index.html file with Conway's Game of Life implementation:

I've created a complete, self-contained Conway's Game of Life web app in a single `index.html` file.
