/* ============================================================
   STERLINPRIME — AUTH THEME (standalone stylesheet)
   Shared by login.html, register.html, forgot-password.html

   Desktop (>900px): two-column split screen — dark brand panel
   on the left, form panel on the right.

   Mobile (<=900px): brand panel is hidden entirely. Only the
   form shows, as a centered, elevated/floating card on a
   full-bleed branded background.
