Ah! Thanks for the report. I suspect this is a browser issue. What browser you on?
I was on Firefox, but I just popped it open on mobile and it looks beautiful there. I suspect Chrome will do it, too. Sorry for the false(ish) alarm!
No worries at all! I have fixed and patched the build to crisply render on Firefox as well. I want it to work on all the browsers! Thanks again for the bug report.
