keras_hub/src/models/flux/flux_presets.py is just presets = {}, and there's no hf:// conversion path either (no flux entry in preset_loader.py's model_type dispatch). FluxTextToImage's own docstring uses from_preset("TBA", ...) as a placeholder.
tools/checkpoint_conversion/convert_flux_checkpoints.py exists but looks stale, it imports a Flux class that no longer exists (renamed to FluxBackbone)
