Hi! I programmed this theme to render posts using Tumblr's NPF object definitions (what Yahoo meant by "next-generation PDF", believe it or not!).
Sadly, this forced me to make post rendering dependant on client-side Javascript. I don't like it either! I'm usually very against it, but Tumblr posts are structured in such a way that required this compromise.
If you see this message, you are seeing a fallback "noscript" version of the page. Some posts may render incorrectly, and JS is sadly required for the full experience.
