   KUA Establishments — brand layer on top of Bootstrap 5.
   Only two brand hues are used: green (--kua-green) and
   red (--kua-red), plus neutral paper/white/ink for
   background & text. No other colors are introduced —
   Bootstrap's primary/danger variables are remapped to these
   two so every standard component inherits them.
