   Sentiment Analysis — themed to the Mzalendo palette.
   Built entirely on the shared design system (core.css tokens): spacing,
   radius, shadow and type scales only — no raw hex, no ad-hoc rem values.
   Brand red (negative) / green (positive) are reused as semantic sentiment
   colours; neutral uses the grey scale. Palette unchanged.
