/* Optimal Trend - Benchmark Metrics page CSS
   DP4 Wave 2 refactor 2026-05-24
   Depends on optimal-design-system.css for chassis tokens and primitives.
   No tree panel (plant-wide reference page).
   Chart-region exception: zone-A/B/C/D badge colours and the summary-count
   text colours preserve the canonical red-amber-green-teal traffic-light
   scale; documented inline at each declaration. */
