// Discover > For You — dedicated, ordered layout for the For You tab.
// Unlike Home / Editor's Picks (uniform album carousels from
// HomeState.sections), For You mixes album carousels, a track
// carousel, and artist carousels, so it renders from ForYouState.
// Sections hide themselves when empty.
//
// Reuses the shared cards/carousels — no new card components here.
// Qobuz Mixes, Radio Stations, Spotlight, and the reco-DB sections
// (More from library, Rediscover) are later increments.
