/* ==========================================================================
   Zorvex SNS Listening — dashboard styles

   Colour roles come from the validated reference palette:
     · magnitude bars  -> single-hue blue sequential ramp
     · sentiment       -> diverging blue <-> red with a gray midpoint
     · lead grades     -> ordinal blue ramp (monotone lightness, validated)
   Every palette used here passed scripts/validate_palette.js in BOTH modes.
   The gray sentiment midpoint sits under 3:1 by design, so the relief rule
   applies: it always ships with a visible direct label and a table view.
