Static, in this shop, means the page is already a page. HTML, CSS, a little JavaScript. The server does not assemble it when you show up. It hands you the file.
WordPress is the opposite on purpose. It is a system for changing pages often, with a login, plugins, and a database. That is useful for a newspaper. It is a lot of machinery for a plumber who updates a phone number twice a year.
A finished page can still look like anything. The shop site I built for my dad’s company does not look “techy.” It looks like a contractor site. The difference is under it: no database on every visit, no plugin patch on Saturday, no admin login for someone to hammer.
You own those files. If we stop working together, you still have a website. That is harder to say about a builder license sitting in an agency account.
