Binary Golf Grand Prix 4

This year I finally managed to complete an entry for BGGP. It's nothing fancy, just a quick take on a self-replicating HTML file. The challenge is a self-replicating file which must make one copy of itself, not run that copy, and display or output the number 4. I figured a self-replicating HTML wouldn't be too much trouble, but seeing just how small I could get it would be interesting, for sure.

My final result is a 123 byte file, which displays the number four in the browser, and downloads an exact copy of itself to a file named 4 in your downloads directory.

We are able to get this as small as it is by using the variable d to represent document at two places in the file, not specifying a data type in the download, and not closing the body tag. I am still hunting for other possibilities to shave off another byte or two.
