The theme you see here is called “Portage”. It’s a take-off on the “Atticus Finch” theme that I developed a long time ago to use on my own WordPress blogs. It’s currently in active development. You can clone it from my Gitea instance.
I originally conceived of Atticus Finch as an old-fashioned, monotone, minimalist design. However, I do tend to add clutter. Portage is my attempt to get back to my original idea for my own theme.
