/* ============================================================================
   AI HIVE DASHBOARD — Design Contract v3
   Palette: Infrastructure Steel (forge-brand generated from proposal #5)
   Typography: Geist + Geist Mono (Vercel pattern)
   Layout: quantifai-style sidebar + content
   Theme: Light-default with dark toggle

   Brand tokens (--brand-*) come from brand/output/ai-hive.css, loaded first.
   This file maps dashboard-specific semantic tokens (--state-claimed, --cat-architecture, etc.)
   to brand tokens. Swapping the brand kit only requires regenerating ai-hive.css —
   no edits to this file.
