   RORO UI — design system layer
   Loaded after style.css. Redefines the design tokens that the rest of the
   app already consumes (430+ var() references, 138 tokenised rgba channels),
   then modernises the shared components on top.

   Direction: functional logistics UI — light neutral surfaces, one restrained
   accent, no metallic gradients, no uppercase button shouting.
   Mobile-first; breakpoints layer upward.
