   Shared styling for the public portal error pages:
     error.aspx          (admin / default / catch-all, audience-adaptive)
     ClientError.aspx    (client portal area)
     LinguistError.aspx  (linguist portal area)
   One copy here so a tweak lifts all three. See project_portal_auth_session_model.
