A personal site is a good place to practice restraint. The temptation is to build every future idea into the first version, but small pieces make the work easier to understand and easier to replace.
A shell owns the page frame. A lockup owns the identity mark. A card owns a post preview. None of those pieces needs to know too much about the others, which keeps the project friendly when it is time to revise the design.
Comments as orientation
Comments are most useful when they explain intent. A comment saying that a link renders a link is noise; a comment explaining why the homepage positions the lockup differently from blog pages is a map.
That distinction matters here because the site is meant to stay readable for a junior developer and for future agents working without the full conversation history.
