@leroy that was actually my first thought, but writing HTML and CSS by hand requires some work if you wanna end up with something decent looking and that doesn't break on some devices. Granted, this is way easier than let's say 15 years ago thanks to stuff like flexbox and CSS grid, but using a template provided by a static site generator is even more convenient. There's indeed some friction on the process of picking a static site generator but after that it's smooth sailing.
