But the article in ai-7-days reverts to the layouts from _default. I have layouts defined for other sections (sorry I had to censor them out) and these work as I expect - layout folder has the same name as the content folder, and the layouts are taken from there.
What might I be doing wrong?
I tried changing the names of the folders to something that was further in the alphabet, to have no hyphens - that didn’t help.
You can add a layout file in layouts/_default/blafasel.html and then add in the frontmatter of the page you want to style layout: blafasel. This will apply that specific layout. And change the filename back to index.md.
