+## Intended use & limitations
+
+    Purpose: Educational decision assistant for 4th‑down scenarios.
+
+    Not for wagering or real‑time coaching; relies on historical
+    probabilities and inherits assumptions from nfl4th.
+
+    Weather and wp_punt imputation introduce simplifications; apply domain
+    judgment when using recommendations.
