I've read your messages and I'm taking into account all the points you mentioned.
@Thaddy, what do you mean by gray theme?
@markov
Well, I'm more or less familiar with your current system. However, I don't think it's the most suitable for the web. But I'll note this request, study how the template system works in detail, and update it.
By the way, yes, JavaScript isn't banned, but I think it's pretty useless in this use case.
Oh, and I added a light mode to my website quite a while ago...

I'm going to look at (and study) the design of several programming sites, including Python. I'll pay attention to the points you highlight to best align with your idea. I need to find the right balance between aesthetics and functionality.
Thank you all for your feedback! However, I must inform you that development will take slightly longer than I originally imagined, as I also need to update the Pascal code.
PS: Would a package manager for Free Pascal be a waste? I mean, for later use, it could modernize the language. All we need to do is impose a library structure to be respected on the Git repository, and then on our side, we have a server that simply maps library name to URL and takes care of installing the library.
