+While this {{ long_term_forecast_years }}-year forecast establishes a testable predictive baseline, understanding the true bounds of this decline
 requires accounting for inherent subsurface uncertainty.
 To explore how variations in reservoir geometry might accelerate or delay the onset of this long-term drawdown, the
 following sensitivity analysis expands our single baseline into a predictive envelope.
