/* ============================================================
   THE LATTICE — Lexicon page (/lexicon)

   A reference glossary, not a marketing page: short intro band on
   navy (matching /apply's pattern), then a single-column reading
   body on a light ground. Terms are rows separated by hairlines —
   no cards — consistent with the "no card borders" rule in
   brand-tokens.css. Callouts reuse the blue-rule panel from the
   source PDF rather than inventing a new treatment.
