/* InvestGood expansion — layered on top of the CAS foundations.
   Color scheme: illuminated-manuscript pigments on a cream (vellum) ground.
   The spectrum draws from historical pigments — verdigris, orpiment gold,
   vermilion/minium, lapis ultramarine, and Tyrian purple.

   NOTE: these pigments are BRAND colors only (the logo underline gradient and
   the verdigris accent). Issues/causes are NOT color-coded — never map a hue
   to a cause category in product UI; use ink and the score scale instead. */
