   Design tokens ("Imperial Topaz" palette), CSS reset, typography and
   layout primitives shared across the whole site.

   Palette notes:
   The brief specified an "Imperial Topaz" theme with two valid anchor
   colors (--gold, --amber below). The gemstone itself runs from deep
   honey-gold through burnt-sherry orange into a dark mahogany-brown, so
   the remaining tones were chosen to complete that family rather than
   default to an unrelated color.
