- New prefs: visualizer_mode (on/dim/off, saved on every click) and color_visualizer_gray (None = keep the derived alternateBase look). - VisualizerWidget takes prefs (optional, so existing call sites/tests keep working); restores its mode at startup and validates junk values. - New "Visualizer (gray mode):" row in the Preferences color sliders; theme.default_gray mirrors the widget's 0.88-lightness derivation so an untouched slider shows the current appearance. - TransportBar.refresh_theme() repaints the visualizer so slider drags preview live.
