   Markor marketing — Millwork-first (2026-07).
   Tokens live in tokens.css (generated from modulus-core). The
   short-name vars used below — --bg, --text, --accent, --sans,
   etc. — are declared there as aliases to the canonical
   --color-* set.

   Type system matches the Millwork app: ONE FACE (Nunito Sans),
   hierarchy carried by weight + size. No serif, no mono.

   Shared chrome (.site-header, .button*, .hero-*, .site-footer,
   .product-*) is also used by /chatdfh — keep class contracts
   stable when editing.
