+    "FIRMS fire hotspots and internet outages use heapq.nlargest() instead of full sort — faster processing of 60K+ records",
-    "Docker networking: CORS_ORIGINS env var properly passed through docker-compose",
+    "Ship counts in left panel memoized with single-pass loop instead of 3 separate filter calls",
-    "Start scripts warn on Python 3.13+ compatibility issues before install",
