Only other comment I have is that alt text should be added on quite a few of the images

Thank you for the review

Yes, I initially wanted to go through and add one for each image, but I think it'll be better as a task on its own

I'll address the rest of these really quick

Going to merge this now. If anyone sees anything strange, please let me know.

We'll follow up on some more accessibility changes later.
