What It Does

1. ✅ Detects FACEIT match rooms automatically
2. ✅ Fetches match players via the official FACEIT Data API
3. ✅ Fetches basic stats (Elo, Level, K/D, Win Rate)
4. ✅ ADR windows: last 10/30/100 matches + date when the Nth match occurred
5. ✅ Activity: games/day over last 7d/30d/90d windows
6. ✅ Shows clean popup with stats
7. ✅ Works on any FACEIT match room page

What It Doesn't Do

• ❌ No demo parsing
• ❌ No MongoDB
• ❌ No complex threading
• ❌ No authentication
• ❌ No advanced analytics
• ❌ No Docker

The Point

Build THIS first. Add features later.

Next Steps

1. Minimal knobs (env var) for API host
2. Optional: cache-busting/expiry
