Artist image resolution was hitting musicbrainz.org with 10
concurrent unthrottled requests per search — enough to trigger
MB's rate limit rejection. Two fixes:
Backend: add dedicated 1 req/s RateLimiter for MB url-rels fetches
in ArtistImageProvider. Each fetch waits on the limiter before
the HTTP call. Results are cached 30 days so repeat lookups are
instant.
Frontend: switch loadArtistImages from concurrent fire-all to
sequential await loop. Each artist image loads one at a time,
images appear progressively as they resolve instead of all
failing from rate limit rejection.
