- LiveSearch: replace SlidersVertical with TextSearch for advanced search
- AlbumHeader: add Highlighter icon for artist bio button
- PlayerBar: remove unused lyrics/mic button
- components.css: album-detail-badge always opaque (accent bg, white text)
- theme: Middle Earth — remove sidebar stripes, fix queue/artist/bio contrast
- theme: Toy Tale — fix muted text, queue tabs, sidebar labels, divider
- theme: Tetrastack — brighten purple/blue palette, raise text-muted contrast
- theme: Horde & Alliance — remove repeating sidebar line pattern
