/* Discovery Loop shared design system (D-025).
   Language borrowed from the Clearlaw obligations-tracker mockups: warm paper
   surfaces, serif headings (legal gravitas), sans UI, mono for identifiers and
   numbers, semantic color used sparingly as badges/accent bars. Variable NAMES
   are kept identical to the earlier per-page palettes so existing markup and
   inline styles keep working — only the values and components changed. */
