⚠️ Important Notes

1. Placeholder Files Needed

Replace these placeholder files with actual content:

/public/resources/pitch-deck-template.pptx - PowerPoint template
/public/resources/example-pitch-deck.pdf - Example PDF

2. Payment QR Image

Still needs to be added (from previous setup):

/public/images/payment-QR.png - For on-spot payment collection

3. Role Assignment

Remember to manually assign staff/admin roles:

Firestore → registrations → [user-uid] → role: "admin" or "staff"

4. Security Rules

Update Firestore security rules to allow:

Staff/admin to write to checkins collection
Anyone to read checkins collection (or restrict to staff/admin)
Team leaders to update pitch deck fields

Example rule:

match /checkins/{checkinId} {
  allow read: if request.auth != null && 
    (get(/databases/$(database)/documents/registrations/$(request.auth.uid)).data.role in ['admin', 'staff']);
  allow create: if request.auth != null && 
    (get(/databases/$(database)/documents/registrations/$(request.auth.uid)).data.role in ['admin', 'staff']);
}

🆘 Support & Troubleshooting

Common Issues

QR Scanner Not Working:

Check browser camera permissions
Use HTTPS (required for camera access)
Try manual UID entry as fallback

Leaderboard Shows Zero Scores:

Ensure judges have submitted scores
Check score field names match (milestone_one_score, etc.)
Verify score structure: { [judgeUid]: [s1, s2, s3, s4, s5, timeBonus] }

Pitch Deck Upload Fails:

Check file size < 10MB
Verify file type (PDF/PPT/PPTX)
Ensure user is team leader
Check Firebase Storage rules

Analytics Shows No Data:

Ensure checkins collection exists
Check that staff have scanned QR codes
Verify Firestore permissions
