/* THIS PAGE SCROLLS THE DOCUMENT, and that is a deliberate second attempt.
 *
 * `body` is `overflow: hidden` globally (style.css) because the app shell is a
 * fixed-height terminal whose views scroll internally. /admin is not inside that
 * shell, so it inherited the restriction with none of the compensation and could
 * not be scrolled at all.
 *
 * The first fix made `.admin` its own fixed scroll container. That restored
 * scrolling and broke pull-to-refresh, because the browser's pull-to-refresh is
 * bound to the ROOT scroller: a fixed inner element can never trigger it, and no
 * amount of overscroll tuning changes that. Reimplementing the gesture in JS
 * would have been a worse version of something the platform already does.
 *
 * So the restriction is lifted for this page instead. `:has()` scopes it to the
 * admin view only, so the app shell keeps its fixed-height behaviour untouched,
 * and the document is the scroller again — which is what pull-to-refresh needs.
