How does the baseline calculation work?

The `calculate_baseline_requirement` tool uses the Holliday-Segar method for pediatric patients and a standard milliliters per kilogram ratio for adults.

What environmental factors are considered?

The engine accounts for fever (temperature above 38C), physical activity duration, altitude elevation, and breastfeeding status.

Is there a minimum fluid recommendation?

Yes, the `get_final_daily_target` tool enforces a safety floor of 2.5 liters per day to assist in kidney stone prevention.
