   Direction: soft rose editorial RTL portfolio. Deep rose + blush + pale pink,
   white cards. Signature: the "folio" — an engraved botanical seal that also
   marks each evidence card. Names of the tokens are kept from the original
   design system so the layout rules below do not need rewriting.
