“Superfluous” it is! Thanks, @tehstu and @CptSuperlative, and to everyone who gave suggestions.
Working on it over holiday break, gradually rebuilding my personal site with it as I build up Superfluous itself. It’s…actually really good for my needs?! I still feel sheepish about building an SSG from scratch, which is clearly unnecessary, but it’s fun — and I’m a firm believe that fun is reason enough!
