// Award "See all" listing — QML port of award/AwardAlbumsView.slint. Route
// "awardalbums".
//
// A search box over the LOADED set, the award name as the page title, and an
// explicitly paginated grid over `/award/getAlbums`. Same four exclusive body
// branches as the landing
// page, in the reference's order: loading · error+retry · no-results (a search
// that matched nothing) · the grid.
//
// The search is CLIENT-SIDE over what has been paginated in — 1:1 with the
// reference, which does not re-query for this box either. That is also why
// load-more is suppressed while a query is active: appending pages the user
// cannot see, to filter them out again, is work with no visible result.
//
// Every number, filter and page in the document comes from src/award_qt.rs;
// this file renders and reports scroll, nothing else.
