   NEX auth gate — ports the SCC full-page access gate to the NEX surface.
   Default-VISIBLE (fail-closed): if nex-auth.js or this stylesheet fails to
   load, the gate stays up rather than flashing the NEX stage. nex-auth.js
   removes it only after the ZITADEL OIDC PKCE flow returns a valid bearer.
   Mirrors zenna-ops-dashboard/commerce/gpu-farm/sovereign-control-center.css
   (CCD-B-v2-FE) — re-skinned for NEX's ice-blue/charcoal aesthetic.
