  75/-- Benefits of supersymmetry:
  76
  77    1. **Hierarchy problem**: Cancels quadratic divergences
  78    2. **Gauge coupling unification**: Couplings meet at ~10¹⁶ GeV
  79    3. **Dark matter candidate**: Lightest superpartner (LSP)
  80    4. **String theory**: Requires SUSY for consistency -/

  90/-- Standard SUSY breaking scenarios:
  91
  92    1. **Gravity-mediated**: Breaking in hidden sector, gravity transmits
  93    2. **Gauge-mediated**: Breaking transmitted by gauge interactions
  94    3. **Anomaly-mediated**: Breaking from conformal anomaly
  95
  96    All involve a "hidden sector" where SUSY breaks. -/
