Specifies header search bar (debounced, URL-synced ?q=), /search page
with three sections of top-10 reusing library components, three
overflow routes (/search/artists, /search/albums, /search/tracks)
backed by createInfiniteQuery. Track click triggers playRadio with
seed via a new /api/radio stub that returns the seed alone (M4 fills
in real similarity-based selection later, response shape final). Adds
+queue button on TrackRow and AlbumCard via new enqueueTrack /
enqueueTracks player-store actions.
