Form Architecture with BLoC

• Manage form state in a dedicated FormBloc — NOT in widget setState
• Each form field maps to a property in the BLoC state
• Validate on field change (real-time) or on submit (batch) depending on UX requirements
• Emit FormSubmitting, FormSuccess, FormError states for submission flow

Form Events

• FieldChanged(field, value) — update a single field in state
• FormSubmitted — trigger validation and submission
• FormReset — clear all fields and errors
