+# A reference soundtrack that is not already at the audio VAE's 32 kHz is resampled with `torchaudio`, which is the
+# only thing in the `ref2va` path that needs it — and it is easy to miss, because a 32 kHz reference skips the
+# resample entirely. Both halves need it: the conditioner's `setup` step prepares the same waveforms this one does.

 # Pinned to the version the MiniMax-H3 parity work was verified against: the Qwen3-VL processor decides the vision
 # patch count, so a different minor changes the conditioning.
