/* ============================================================
   Data product pages (/data/*.html)

   The page bodies are generated upstream (brochure builder) and carry both
   component classes and inline `var(--…)` references to a small local token
   set. This file re-points that token set at the Intnax design system and
   restyles every component in the site's idiom — warm paper, hairlines,
   single teal accent, display/body/mono trio from site.css.

   Loaded only by /data pages, so the local tokens live on :root.
   --ink and --border-strong also exist in site.css; they are aliased to the
   same values there, so site chrome (header, footer) is unaffected.
