Codeforces Torture 作者： Mubtasim Sajid, Cards29

How it works:
1. Enter your Codeforces handle & preferred rating range (e.g. 800–1200).
2. The extension fetches unsolved problems from the Codeforces API tailored to your range.
3. Any attempt to visit a non-Codeforces site is blocked by a full-page overlay.
4. Solve the problem on Codeforces & the block lifts automatically.
5. A new daily challenge is assigned each day with a browser notification.

Features:
- Random unsolved problem selection using the official Codeforces API
- Configurable rating range (min/max difficulty)
- Automatic daily problem assignment with alarm-based scheduling
- Real-time Codeforces login detection
- Cached problem sets for fast offline access
- Lightweight - only requests Codeforces API data, no user data collected or transmitted

Perfect for:
- Competitive programmers who procrastinate between practice sessions
- Students preparing for contests who need enforced focus
- Anyone using the "don't break the streak" method to stay consistent

No tracking or data collection. Just you & Codeforces!
