I just spent a fair while barking up the wrong tree on this and figured I should just ask the experts.
I’ve built my Jekyll site using the minimal-mistakes theme and am quite happy with it. I would, however, like to be able to have it look different and change content in particular contexts. I have two domains, one personal and one professional. I would like the professional site to contain a subset of the site content and use a different skin and logo. I feel like it should be possible to reuse content rather than maintain two separate sites. I’m fine with the build generating separate site files, but I’d like to stick to unique source files.
