I have figured this out, please see my own reply for a followup question.
I haven’t yet been able to find a good way of doing this just yet: We’re looking at potentially replacing our in-house static site generator with Hugo. Our website is translated into roughly 20 languages across about 8 different templates. Most of them are similar which we could bridge with partials, but my question is right now we use json files to handle translations. What could be a good way of doing translations that populate templates? Front Matter?
