Within the same name-match tier, the US Teenagers (MB score 100) ranked above the FR Teenagers (MB score 93) because the tiebreaker used OriginalScore. But the FR band is globally more popular (1.3M vs 23K listens) and has the higher blended score (82 vs 72). Changed the within-tier tiebreaker to use the blended Score, which already incorporates both text relevance and popularity. This ranks the more well-known artist first among same-named exact matches. Added OriginalScore field to MBArtist (json:"-" so it doesn't affect the frontend) to preserve the pre-reranking MB score for potential future use.

Architecture
YellowJacket uses the Wails v2 framework to bridge a Go backend with a TypeScript/Lit frontend running in a native webview.
- Go backend -- audio decoding and playback (beep), library scanning, SQLite database, cover art serving, TOML configuration
- TypeScript frontend -- Lit web components, singleton stores with reactive controllers, Web Awesome UI components
- Communication -- bidirectional event system via Wails runtime; backend is the source of truth
- Database -- SQLite (pure-Go driver) with type-safe queries generated by sqlc; MusicBrainz-style data model (artists, artist credits, recordings, release groups)
- Config page -- HTMX-based, loads HTML fragments rendered by Go templ templates
