/* =============================================================
   Dyad Docs landing — tokens & components
   Scientific-poster / Swiss-editorial feel. Everything is a
   hairline, one saturated accent (indigo), and the signage
   layer is all mono uppercase.
   Uses VitePress's existing Inter / JuliaMono stack — the
   design system's Rale Grotesk is intentionally not loaded.
   All rules gated behind `.dyhome` so other docs pages remain
   unaffected.
