/* ══════════════════════════════════════════════════════════════════════════
   Campaign Analytics  --  Enterprise v3 (2026)
   Follows Material Design 3 (Material You) principles:
     - Tonal color surfaces instead of semantic bar stripes
     - 3-level type scale: label / value / sub
     - Tabular-nums for all metric columns
     - State layers (hover overlay) instead of box-shadow changes
     - Accessible contrast on all health states (WCAG AA)
