"""Fetch everything else Ideogram 4 needs to run this quantized DiT.

This GGUF is the *quantized DiT only*. You also need the text encoder, VAE,
configs, and the custom inference package. Run this once.

Requires your own access to the GATED base repo `ideogram-ai/ideogram-4-fp8`:
  1. Accept its license at https://huggingface.co/ideogram-ai/ideogram-4-fp8
  2. `huggingface-cli login` (or `hf auth login`) with a token that has access.
