/* ============================================
   TheBigBoard — Unified Design System
   Single source of truth for all pages
   ============================================

   ACCENT COLOR DECISION: Amber #f59e0b (SCIF identity)
   -------------------------------------------------
   Rationale:
   1. SCIF aesthetic — amber signals operational
      intelligence, urgency, and classified-system UX.
   2. Consistency — the landing page established amber
      as the brand accent. All pages now follow this.
   3. WCAG AA — #f59e0b on #060608 yields sufficient
      contrast for headings and interactive elements.
   4. Green (#22c55e) = live/active states only.
      Red (#dc2626) = critical/alerts only.
      Amber = primary UI accent across all pages.

   MIGRATION NOTES
   -------------------------------------------------
   - This file replaces the :root blocks in both
     shell.css and dashboard.css.
   - Page-specific CSS (battlefield.css, iran.css, etc.)
     should reference these variables and may define
     page-scoped overrides with --page-* prefixes.
   - Drop Roboto everywhere. Inter = UI, IBM Plex Mono = data.
