# Per-channel latent statistics of the LTX-2 autoencoders, the `latents_mean` / `latents_std` buffers of the `vae`
# and `audio_vae` of `Lightricks/LTX-2` rounded to six decimals (the buffers are bfloat16, so this is well inside
# their resolution). `LTX2ModularPipeline` serves them from its `latents_mean` / `latents_std` /
# `audio_latents_mean` / `audio_latents_std` properties when the autoencoder they belong to is not loaded, the same
# fallback the compression-ratio properties make for their components.
