/* reference.css — the reference's theme stylesheet. It opens with the :root block
   that redefines every token declared in reference-head.css (the palette, type
   scale, spacing and shape), then styles each surface in the reference's class
   vocabulary. The Colors and Typography settings re-declare those tokens after this
   file (snippets/theme-colors, snippets/theme-fonts), and transplant.css adds what
   the reference never needed (platform surfaces, dropdowns, state classes).

   The register comes from restraint: an ivory ground, a light header carrying the
   mark in the accent cocoa, a serif display voice (Cormorant Garamond, with Noto
   Serif SC for Chinese) over Jost small caps, square controls, and colour arriving
   through the photography. Every colour is decided once, in :root.

   Adapted from the reference in two places, both marked: the logo's crop window is
   scoped to .logo--mark (the built-in mark only; an uploaded logo renders whole),
   and the narrative comments were rewritten. */
