/* Design tokens — a validated color system (dataviz skill reference palette),
   not picked by eye. Sequential blue for brand/primary actions; the four
   status hues (good/warning/serious/critical) are reserved for state and
   never reused as decoration. Every status badge still carries a visible
   text label — color is never the only signal, since warning/serious don't
   clear high contrast on a light surface by design (their mitigation is the
   label, per the palette's own accessibility note). */
