+# NOTES
+###############################################################################
+#
+# Expected Results:
+# ✓ All generations complete successfully (status = "success")
+# ✓ Each generation has unique ID and output image
+# ✓ Aspect ratios are correctly applied
+# ✓ Processing times are recorded (typically 3-15 seconds)
+# ✓ Pagination works correctly
+# ✓ Status filtering works correctly
+#
+# Common Issues:
+# ⚠ Generation may fail with Gemini API errors (transient)
+# ⚠ Processing time varies based on prompt complexity
+# ⚠ First generation may be slower (cold start)
+#
+# Tips:
+# - Use "Poll until success" for Step X.2 requests
+# - Variables are automatically extracted from responses
+# - Check response body to see extracted values
+# - Most generations complete in 5-10 seconds
