This is a meta question of sorts. I do almost no font manipulation in my CSS except for a tiny smattering of size changes on headings and the the like. Right now I'm working on a fairly involved Jekyll generated site (it takes 2-3 mins to render. 8-P) and am reconfiguring the pages, structurally but the font on my CJK (Chinese, Japanese,Korean) text has mysteriously changed from serif to sans. I've combed through my code, the theme code, etc and can find no reason for this change. Using web dev inspector on the text in question, there are no font styles affecting this text. What could be causing this change? What else can I do to try to figure out what's going on?
