Fix (the reported bug):
- Deezer's /artist/{id}/albums omits the artist object, so discography album cards had an
empty artist name → the download modal fell back to the literal "Unknown Artist", which
poisoned the yt-dlp search ("Unknown Artist <album>") and its artist/channel filter, failing
with "Nicht eindeutig gefunden".
- deezerLookupArtistAlbums now backfills the known artist name (we're on that artist's page).
- openDlModal now defaults album cards to an ALBUM download (was always Track), so a one-click
download no longer grabs an album as a single track named after the album.
Rename (requested cleanup, dependency-checked so nothing breaks):
- All frontend itunes* identifiers → deezer* (functions, the ItunesItem-shape field keys
itunesData/itunesArtistId/itunesFanCount/itunesId, the itunes-album-detail route + DOM ids,
the badge-itunes CSS class). The backend reads none of these fields, so the boundary is safe.
- Verified: build passes; route/DOM-id/CSS producer↔consumer all consistent; only the factual
"Apple's iTunes /search 403" comments keep the historical name. SW ns-v62.
