📝 **Task:** Predict what this Python snippet prints. ```python stt = 280 claude_ttft = 650 # streaming + cached prefix + effort=low + Sonnet tts = 470 total = stt + claude_ttft + tts cap = 1500 print(f"total={total}ms") print("under_cap" if total < cap else "over_cap") print(f"headroom={cap - total}ms") ``` 📋 Implement the function above. Tests run automatically. 💡 **Hint:** Re-read the theory if stuck.
