/* =========================================================
   Hutgrabber — Custom theme layer over Risotto
   Nord palette · Jersey 25 (display) · Literata (body)

   Surface model (IMPORTANT):
   Risotto paints .page__body with --off-bg (base01). Any
   "raised" element (code, fields, buttons, cards) must use
   --inner-bg (base02) so it always contrasts the body in
   BOTH light and dark mode. Never use raw base01 for surfaces.
