echo "======================================"
echo "  Why was this happening?"
echo "======================================"
echo "The worship list routes were not checking authentication."
echo "The frontend WAS sending tokens correctly, but the backend"
echo "wasn't configured to require or verify them for these routes."
echo ""
echo "Now all modification routes (POST/PUT/DELETE) require a valid"
echo "JWT token, which fixes the 403 Forbidden error."
