/* VisaSpecs — document-reference theme + spec-lookup widget styles.

   Palette comes from site.config.json (violet primary, crimson accent — a
   "spec sheet + verification stamp" feel, distinct from the sibling tools
   on this domain). The engine owns light/dark surfaces; we only style the
   widget and a few prose extras. */
