    - **Algorithmic Risk Score (A-Risk):** **{raw_scores['A_Risk']:.2f}**
    - **Platform Diversity Index (D-Index):** **{raw_scores['D_Index']:.2f}**

    ### 📝 Interpretation
    *Your C-Score is based on logarithmically scaled time, reflecting diminishing returns. Your A-Risk is based on raw time, reflecting concentrated attention.*
