// — typically a domain you've pointed at Start Tunnel. Magic-link
// sign-in emails interpolate this URL into the verification link:
//
//   Click here to sign in: https://recap.example.com/auth/verify?token=...
//
// Without this set, magic-link emails contain a link to localhost or
// to the StartOS internal hostname, neither of which work for a user
// reading the email on a different device.
//
// Only meaningful when recap_mode === 'multi'. In single mode the
// value is ignored — there's no magic-link flow.
