The word and the page title were split by a <br> only, which a copy,
textContent and an assistant read as "PreviousWhat the packs do not
hold". The override keeps Starlight's look, spaces them, names each link
by direction and page, and makes the pair a navigation landmark.
Generated and built pages read without the stylesheet, skipping hidden,
aria-hidden, scripts and styles: no step or figure text read twice, no
counter glued to a label, no empty picker, every laid out box spaced.
The build's filter box is compared with the generator's through node.
