apply_declared_extra_args(
sampling_params: OmniDiffusionSamplingParams,
declared_params: frozenset[str],
user_kwargs: dict[str, object],
) -> None
Route pipeline-declared request params into sampling_params.extra_args.
Both online serving and offline examples call this so that model-specific keys (e.g. cfg_text_scale for BAGEL) end up in extra_args instead of being silently dropped.
This is a no-op when no declared params are present in user_kwargs, so it is safe to call on non-diffusion (e.g. AR) sampling params whose extra_args defaults to None.
