Customer registration page

hi @dan.woda , i’m looking at this page Customize Classic Universal Login Pages with Lock or SDK, but i cannot see how/where to custom signup page. is signup page the same as login page?
i would prefer only to use a custom signup page including more user info eg company, phones and terms etc. and keep using the universal login page.
but under branding i can only see changes can be made to the login page instead of signup page.
