/* ReviewFlow shared design system
   Signature device: the "star meter" — a horizontal 1-5 gradient bar
   used everywhere a rating appears, instead of generic donut charts.
   Palette is grounded in the product's own subject matter: ink for
   trust/authority, a warm gold reserved ONLY for ratings/stars so it
   stays meaningful, teal for resolved/positive, brick for alerts.
