/* Jinjer Fuel — shared visual language.
   Tokens and component classes are deliberately matched to the ACTUAL
   Jinjer production frontend (apps/frontend-web in the jinjerSales repo:
   its Layout.tsx app shell, WaAnalyticsDashboard KPI/card grammar,
   AgentLeaderboardView podium/table/segmented-control patterns, and
   IntelligenceHealthPage status-badge convention) -- not approximated
   from screenshots, and not modelled on any other internal tool. Values
   below are the same Tailwind slate/indigo/emerald/amber/red palette
   that frontend actually ships. No framework dependency -- plain CSS,
   matching this app's existing lightweight, no-build stack. */
