/* ============================================================
   v6 Tempo cluster — number input + slider + Tap-tempo button
   ============================================================
   Goal: replace the coarse range-only tempo with a precision-first
   control. Number input is the canonical entry (any BPM 40–240,
   decimals allowed); slider is for quick drags; Tap is for musicians
   who think in pulse, not numbers.

   Density: fits inside the existing .playback-settings row.
