/* SHIN Zürich — one stylesheet for the whole site.
   Direction "Season & Sea" (approved 2026-09-07): near-black, Cormorant Garamond for display, Jost for text,
   one gold accent taken from the lacquer plate of the hero photograph, the 心 mark set in type.
   Mobile-first; every path in the pages is relative so the site serves from a host root or a preview path. */
