• Four dialogue metric rows: Coverage, Range, Avg. Offset, Active Now (with live speaking indicator)

• HoverTip component for consistent tooltips across the app

Changed

Fixed

• Clipped descenders and tight row gap in loudness stats
• Idle channel labels unified to L/R across all panels
• Stats/Layers popover sized to content so labels don't wrap
