This fixture is deliberately short. It contains no h2/h3 headings, so the table-of-contents panel has nothing to list. The layout should still render without breakage — that empty-state path is the whole point of this page.
A short second paragraph reinforces that the article is intentionally brief. The empty-state ToC, the sticky-header collapse on scroll (or lack thereof, since there’s nothing to scroll past), and the single-column body width on mobile are all visible here.
