🔐 Firebase Firestore Kuralları (TEST İÇİN)

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if true;
    }
  }
}

⚠️ Gerçek projede güvenlik ekle!

🎯 GELİŞTİRME FİKİRLERİ

Bunu bir üst seviyeye taşıyalım:

• 🔔 Bildirim sistemi (Firebase Messaging)

• 🧠 AI öneri (bugün ne yapabilirsin?)

• 📊 Grafik (haftalık puan)

• 🧑‍🏫 Öğretmen paneli

• 🎯 Görev listesi (hazır iyilikler)
