Because I had not much else to do this morning and because I felt like it, I figured out how to build the game for the browser and then went ahead and did it. The browser version is 1.0_Web, and it contains the following updates:

• "Licensing" menu links to an externally hosted copy of the "attributions.pdf" file on my website, rather than to the file in the game folder.
•  "Disclaimer" menu link an externally hosted copy of the "content warnings.txt" file on my website, rather than to the file in the game folder.
• Main menu version is stated "1.0_Web" rather than "1.0".

Other than those three things there are zero differences in the source code or files between the browser version and the download version, which has not been changed.

Hopefully this is useful to somebody.
