It can be. But like I mentioned earlier, my personal website is a hobby project I've been running since my university days. It's built with Common Lisp (CL), which is part of the fun for me. It's not just about the end result, but also about enjoying the process.
While precomputing HTML and CSS is definitely a viable approach, I've been reluctant to introduce Node or other tooling outside the CL ecosystem into this project. I wouldn't have hesitated to add this extra tooling on any other project, but here I do. I like to keep the stack simple here, since this website is not just a utility; it is also my small creative playground, and I want to enjoy whatever I do here.
