Firebase Setup

Project Config: Create Firebase project, enable Firestore, Authentication, Functions, Storage. Store firebaseConfig in .env.
Service Binding: Initialize Firebase SDK in React app for Auth, Firestore, Storage, Functions.
Authentication: Enable Email/Password, Google Sign-In. Use custom claims for roles (Student, Faculty, HOD, Admin).
Firestore Collections: students, attendance, classes, sessions, fees, faculty, departments, announcements, assignments, chats, geofences, budgets. Indexes for queries (e.g., attendance by sessionId).
Storage: Configure for file uploads (documents, images, receipts). Role-based security rules.
Security Rules:
Firestore: Restrict by role (e.g., Students read own data, Admin full access).
Storage: Authenticated users only, validate ownership.



General Features

Dashboard: Role-specific KPIs (Attendance %, Fee Status, Faculty Availability) using Firestore queries.
Sessions CRUD: Manage sessions in Firestore, check time/location conflicts, sync with calendar.
QR Scanner: Use [login to view URL] for QR generation/scanning, mark attendance in Firestore.
Geofencing: Store zones in Firestore, validate user location via Geolocation API.
Manual Attendance: Validate codes against Firestore sessions.expiresAt.
Notifications: Cloud Functions trigger FCM for session creation, fee overdue, etc.

Role-Based Features
