/* ============================================================
   AARUSH ECO TECH — PAGE-ESG-ANALYTICS CSS  ✅ PRIMARY
   Page-specific styles for esg-analytics.html ONLY.

   Phase 2 refactor — generated from esg-analytics-page.css

   Load order: global.css → components.css → page-esg-analytics.css

   Notes:
   - No @import (Space Grotesk already in global.css)
   - No :root block (all tokens from global.css)
   - .kpi-card override intentional (elevated bg + gradient top-bar
     vs generic light card in components.css)
   - .pulse-dot ADDED (used in hero badge — was missing from source;
     defined with var(--color-primary) for this page context)
   - Zero dead CSS
