/* =====================================================================
   WMS-FSSCO Dashboard — Design tokens
   A light, professional working palette: white/soft-gray panels on a
   pale blue-gray ground, each module still keeping its own accent hue
   for quick wayfinding (sidebar dots, page accents, hazard badges) —
   just deepened enough from the original dark-theme brights to stay
   legible as text and borders on a light background.
