.description is now used on a <p> (FormDetailPage.tsx), but the CSS only sets margin-bottom. Because <p> has user-agent default margins, the top spacing becomes browser-default and differs from the old <div> layout. Consider explicitly setting the margin (e.g., margin: 0 0 1rem 0 or at least margin-top: 0) so spacing is predictable.

Suggested change

	margin-bottom: 1rem;
	margin: 0 0 1rem 0;
