/* Optimal Trend - Reports page CSS
   DP4 Wave 3 refactor 2026-05-24
   Depends on optimal-design-system.css for chassis tokens and primitives.
   Admin-only page (data-role-restrict on nav, sessionStorage guard in head).
   No tree panel (director call C on methodology brief section 5.1).
   No off-palette colours outside the explicit report-chart exception
   declared inline at the script-template chart-fill palettes. */
