   NEONBET · Auth screen reskin — login / register
   (frontend-redesign-v2 · designer auth.css look)
   ------------------------------------------------------------
   SCOPED to #auth-screen. Restyles the EXISTING production auth
   markup (tabbed login/register overlay) to the designer card look
   on tokens. Every field id, .auth-tab/.auth-form hook, .form-error
   and the bindAuthForms wiring are untouched — Auth.login /
   Auth.register, email-or-username login, 18+ DOB check and JWT
   token storage all keep working. Loaded after style.css.
   No backend / API changes.

   username → password → CREATE ACCOUNT) ended up behind the keyboard with no way

   #auth-screen scrolls with the window, so the keyboard can never trap a field
