/* =====================================================
   RESEARCH ENGINE — public page styles
   Covers every .research-* class emitted by
   renderResearchSections/renderResearchClaims/
   renderResearchSourcesFootnotes/renderResearchRelated in
   controllers.js, plus the hub/list/item page shells in
   templates/pages/research*.html. Uses the site's existing
   design tokens (see :root in main.css) so this matches
   per-tenant theming automatically rather than hardcoding colors.
