About this extension
FocusForces is the ultimate companion extension for competitive programmers and problem solvers on Codeforces, AtCoder, CodeChef, and LeetCode.

Key Features:

⏱ Universal Focus Timer
• Countdown & Stopwatch modes with persistent timer state across browser restarts.
• Danger-zone alerts when under 5 minutes remain.
• Customizable milestone notifications (10m, 5m, 1m, and Time's Up!).

🏆 Multi-Platform Contest Tracker & Reminders
• Live aggregations for upcoming and ongoing contests from Codeforces, CodeChef, AtCoder, and LeetCode.
• "Next 24 Hours" and "All Contests" tabs with urgency badges.
• Reliable background reminders (1d, 12h, 2h, 1h, 30m, 10m, 5m).

🎨 4 Built-In Themes & Zen Mode
• Default, Dark, AMOLED, and High Contrast themes.
• Zen Mode: hides noisy site clutter, headers, and comments for full-width problem reading.

🔍 Scout Problem Tags & Rating Toggler
• Hide problem tags and difficulty ratings to avoid spoilers during practice, and reveal them only when needed.

🐾 Zen Paws (Cat Walk Companion)
• Optional animated SVG companions roaming the bottom of the screen with gentle cursor interactions and paw prints.

🎉 AC Celebration
• Soft celebratory burst and quiet chime whenever you get an Accepted verdict on Codeforces.

🔒 Privacy-First:
• Runs purely client-side. Zero analytics, zero data collection, and zero tracking.
