/* ===========================================================================
   Deteryx landing page
   ---------------------------------------------------------------------------
   The page is set like an inspection report, not a SaaS template: bone paper
   and black ink, one signal colour that only ever means "this was found",
   square corners, hairline rules and a visible column grid. Type does the
   work — a condensed grotesk for headlines, a dot-matrix face for every
   number, a mono for labels.

   Two surfaces alternate: paper sections and `.ink` bands. Components read
   only the semantic tokens (--bg, --fg, --fg-2, --mute, --line), so the same
   component works on either surface without a variant.
   =========================================================================== */
