KycForm + GuardianConsentForm
The applicant KYC form and the guardian-consent branch it triggers when dateOfBirth < 18 years. Both consume the InputField / SelectField / FileUpload / PhoneInput primitives from phases 6.2a–f, so brand overrides re-tint them automatically.
KycForm
Minor detection is client-side only; the server re-validates. Try a date of birth before YYYY-MM-DD to see the guardian banner appear.
