dataset_info:
  features:
    - name: id
      dtype: string
    - name: phase
      dtype: int64
    - name: story
      dtype: string
    - name: position
      dtype: int64
    - name: fragment
      dtype: string
    - name: fragment_id
      dtype: string
    - name: illustration1
      dtype: image
    - name: illustration2
      dtype: image
    - name: annotator_selections
      sequence: string           # was: list: string  ← fix
