/**************************************************************************************************
| 609 Mafia - authentication pages (pages/signup.php: invitation code, sign-up form, closed / done cards)
|
| Everything is scoped under .iz-auth / .iz-auth-body so none of the legacy registration styles in
| site.css (.reg_container / .reg_namebox / reg_para_bg.jpg - the old red, left-aligned table) can leak
| in, and nothing here changes any other page. Same visual language as login.php and the themed auth
| error page: the shared smoke-video background (inc/background.php), the mb.gif hero centred on top,
| one centred dark glass card (--mu-* tokens from site.css).
