/**
 * Registry of email providers offered by the SMTP quick setup card.
 *
 * Adding a provider is meant to be one entry here plus an API adapter:
 * fill in the SMTP relay settings, point at the console OAuth2 provider that
 * issues an access token for it, and implement {@link SmtpQuickSetupApi}.
 * Entries without `oauth` + `api` render as "Coming soon".
