/* ==========================================================================
   NosoGraph homepage — designed landing surface (Stage 2 rebuild).

   Scoped to html.ng-page-home (set synchronously by docs-theme/main.html).
   Consumes tokens.css; generic primitives (buttons, chips, evidence states,
   eyebrows) live in components.css. Material sets html { font-size: 125% }
   (20px root), so display sizes and metadata use px clamps for determinism
   instead of the rem-based text tokens.

   Motion: hero entrance + ambient glow are CSS-only; section reveals are
   gated behind html.ng-motion, which home.js adds ONLY when
   prefers-reduced-motion is not requested. base.css additionally kills all
   animation under reduced motion, so information never depends on motion.
