/* =============================================================
   Silk & Steel — stylesheet

   Two committed fields:
     · LEATHER  — header, hero, the house, paying, checkout, footer
     · PARCHMENT — the catalogue, the product sheet
   One accent (brass). Oxblood is reserved for the primary action.

   Colour, type and spacing are all tokens. Components read from
   field-scoped variables (--bg / --fg / --rule) so the same card,
   panel or button works on either field without a variant class.
