Bug

mmmu_pro_doc_to_text returns an empty string for mmmu_pro_vision: the vision split has no question field, so the standard prompt-construction branch is skipped and the YAML-configured post_prompt ("Answer with the option letter from the given choices directly.") is never sent to the model.

Fix

Default question to post_prompt so the instruction reaches the model for vision-only docs. Standard split behavior is unchanged.
