🔧 How it Works

• Cookie Lifecycle: cookie.json stores iat and expiry; validated on startup & during requests.
• Error Resilience: retries transient errors and refreshes cookies on 401/redirect-to-login.
• Progress Accuracy: uses Instagram’s comment count to calculate percent & ETA.
• Async Efficiency: httpx.AsyncClient with HTTP/2, keep-alive, and RPS limiter.

💡 Tips

• Start with 5-7 RPS to minimize throttling; increase gradually.
• Filenames use local time; switch to UTC by replacing datetime.now() with datetime.utcnow() in main.py.
