- VU needle swings -22..+22deg instead of -45..+45 for a more realistic VU look - Switch from RMS to peak frequency reading so the needle catches musical hits - Faster attack (0.7) and release (0.25) so it swings rather than pinning - Replace explicit grid lines with subtle repeating-conic-gradient ticks - Scope mini progress bar styles to .mini-player; taller (3px), clickable
