/* ==========================================================================
   DashRide — Uber Base Design System Engine (base.uber.com)
   Official Architecture:
   - Core Tokens: backgroundPrimary, backgroundSecondary, contentPrimary, contentSecondary, borderOpaque
   - Spacing: 4px Base Grid (spacing100: 4px, spacing200: 8px, spacing300: 12px, spacing400: 16px)
   - Corner Radius: radius200: 4px, radius300: 8px, radius400: 16px, radiusPill: 9999px
   - Density Modes:
       * Default/Comfortable Mode: Rider passenger apps, public landing, loose spacing (spacing400).
       * Compact Mode (.density-compact / body[data-density="compact"]):
         Admin operational consoles, live telemetry, and data tables.
