+COMPREHENSIVE SMOKE TEST - Real end-to-end testing using actual apps
+Tests both classic (50+ transitions) and beat-matched slideshows with real VRChat data
+Outputs timestamped files to smoke test folder with programmatic verification
+
+THIS TEST PROVES THE SYSTEM WORKS BY:
+1. Using 50+ real VRChat images (no repeats)
+2. Preprocessing to 1080p for performance
+3. Creating 50+ DIFFERENT transitions (no repeats)
+4. Using real audio with beats
+5. Calling actual CLI apps like a real user
+6. Verifying outputs programmatically with frame analysis
