/* ═══════════════════════════════════════════════════════════════════════════
   VYNAKRO ADMIN PORTAL — STYLES
   ───────────────────────────────────────────────────────────────────────────
   Structurally mirrors the MCS Claims-Core admin portal
   (/var/www/mcs/mcs_v8.html). Component vocabulary kept identical
   (.nav-item, .page-header, .card, .metric-card, .btn, .table-wrap)
   so screens can be cloned and re-skinned without restructuring.

   Color overrides (Vynakro green palette replacing MCS navy):
     MCS navy gradient #0B1F3A → #091729 → #060F1C
     Vynakro navy      #002650 → #001830 → #001224 (the logo, 2026-10-06)
     Accent            electric blue #0090F0 (the logo)

   Spec deviation note: design doc VYNAKRO_ADMIN_PORTAL_DESIGN.md §1
   reserved Vynakro green/gold for customer pages and called for MCS
   navy on the operator surface. This implementation overrides that
   choice — operator portal uses Vynakro brand colors. Spec to be
   updated to reflect the override at Phase 5 sign-off.
