Material3 changed the Slider's default inactiveTrackColor to colorScheme.secondaryContainer, which MinstrelTheme does not override -- so M3's baseline purple leaked into both the mini scrubber and the NowPlaying ScrubberRow. Flutter explicitly sets inactiveColor = fs.slate; mirror that by pinning inactiveTrackColor to surfaceVariant (which the theme already maps to slate).
