   Section color spectrum — one distinct, muted-jewel accent per section, used

   color-coded categories measurably speed navigation (NN/g, color-in-UX
   studies) as long as the base UI stays calm — so these are used ONLY on
   icons/chips/accents, never on body text or large surfaces. Hues are held to
   similar saturation/lightness as --terracotta/--purple/--moss so the set
   reads as one family, not a rainbow grab-bag.
