Organization-wide font choices for Wingspan-hosted and embedded surfaces. Email font support depends on each email client's rendering rules; email templates fall back to safe system stacks when a custom font is unavailable.

Organization-wide CSS customization for Wingspan-hosted and embedded surfaces. CSS is applied after the standard Wingspan theme tokens and is not used for transactional email rendering.

Per-direction email delivery configuration. Defaults to WingspanManaged everywhere. Three directions: - ar — invoices, charge receipts, dispute notifications, retry notices. - ap — payable notifications, payout receipts, tax-form delivery. - transactional (a.k.a. operational) — security alerts, MFA
challenges, login notifications. Security-relevant emails default
to WingspanManaged regardless of brand mode and are not delegable.

Per-jurisdiction currency allow-lists at onboarding. Drives the choices presented in embedded onboarding and is enforced server-side at POST /v3/finance/external-bank-accounts. Default (when currencyPolicy is unset): all currencies allowed everywhere — backwards-compatible behaviour. When set, the policy is exhaustive: countries not listed retain default behaviour; countries listed permit only the named currencies. Inheritance: child accounts inherit the parent's policy until they set their own.

Retry-policy customization per direction. ar controls retries for failed AR charges; ap controls retries for failed disbursements.

Security-related customization. Default values are secure-by-default; the entries listed here are caller overrides for organizations with documented security exceptions.
