div

The generic block-level container with no meaning of its own — a box to put a class, a style or a layout on when no semantic element applies — and therefore the element to reach for last, after <main>, <section>, <article>, <nav>, <aside>, <header>, <footer>, <figure>, <ul> and the rest have been ruled out

Not wrong, just silent: a <div> tells assistive technology nothing, which is fine for a grid wrapper and wrong for a navigation. Divitis is the page that is nothing else. Frameworks and utility CSS pull toward it because a <div class=“flex gap-4”> is quick; the rule here is that the layout wrapper may be a div and the thing being laid out should not be. The catch-all page on this site wraps in a <div> and puts the <article> inside, which is the right order.
