+
+**Gemini:** You are absolutely correct, and my apologies for that failure. Your diagnosis is spot on. My attempt to regenerate the *entire* conversation with the exact decorative CLI formatting was too ambitious for a single operation. Generating that much complex, formatted text likely exhausted the API's resource limits (either processing time or response size), which caused the process to be terminated.
