   Insights hub ("/insights", "/insights/{topic}") and article pages
   ("/insight/{slug}").

   Every selector is namespaced under .ins / .ins-* so nothing here can reach
   the shared layout rules in main.css, default.css and responsive.css, which
   are also used by the directory, discussion and membership pages. Those
   globals reset list styles and set h2 to 70px, so the article body restates
   the properties it needs rather than inheriting them.

   Tokens match the home page and directory redesigns.
