IMPORTANT NOTES
- JSON fields must use double quotes:
{"key":"value"} ✅ — {'key':'value'} ❌
- Leave Extra option 1 empty when not needed
validated text for isEmail returns the normalized email (lowercase, dots removed for Gmail)- Each call overwrites previous states — for multiple fields use multiple validator elements or validate sequentially
