+# ZeroGPU (torch 2.9.1, the version ZeroGPU requires). We do NOT use torchcodec: the
+# patches package replaces torchaudio.load with a soundfile (libsndfile) reader before
+# f5_tts imports, so torchaudio's torchcodec path is never touched. torchcodec still gets
+# pulled in as an f5-tts dependency but stays dormant. `spaces` provides @spaces.GPU.
