/* Dark auth look ("Sign in · B · All dark") shared by the pre-login pages:
   /login, /forgot-password, /reset-password and the post-checkout question
   (/billing/payment-complete). Seen by everyone, phones included — no v2 gate.
   Fonts come from the ui_v2 module's static dir by absolute path, so a page still
   renders (system font) if that module is ever absent. */
