   Dealers Marketing — auth (login / signup / forgot / reset)
   Split panel per mockups/login.html. Dark theme.

   elements with inline styles:
     #auth-container      -> display:flex
     .auth-tabs           -> display:flex / none
     #auth-password-field -> display:flex / none
     #forgot-password-link-> display:block / none
     #auth-error          -> display:block / none
