/* =====================================================================
   Pre-sign-in pages (base_auth.html) — sign in, register, forgot
   password, magic links, invitations, 2FA, new-browser and session
   checks, SSO and provider errors.

   Layout: two clear halves at ≥1024px — a dark ink brand panel on the
   LEFT (why Lexlegis) and the light form column on the RIGHT (top bar ·
   card · footer). Below 1024px only the form shows. Form colours are
   tokens from app.css so they follow light/dark; the panel is always dark.
